Win10 boot problems swapping HDDs
I have complicated intermittent Win10 boot problems where I'd like to ask
two questions which come up during debugging and repair. (1) Can I swap a Windows 10 boot HDD from one machine to another to test whether it's the boot drive or the machine that is causing the problem? Or does the MS license issue of the two different machines prevent that? (2) If I put the "maybe bad" Win10 boot HDD in the "good" machine as a second disk, how do I install Win10 onto this second disk using a Win10 ISO file on the good machines' boot drive which is the first disk? In the past I've only installed Win10 on the "C:" drive. Can Win10 be installed on the "D:" drive from a Win10 ISO on the C: drive? |

In the past I've only installed Win10 on the "C:" drive. Can Win10 be installed on the "D:" drive from a Win10 ISO on the C: drive? I've accidentally booted the wrong Win10 disk on a machine, and it didn't seem to hurt Windows 10 (that's not an endorsement of the procedure, mind you). I shut down as quickly as I could, when I realized my mistake. A side effect of such a boot, is hardware detection should take place, and drivers get added. I haven't checked to see if the OS is clever enough to start a new ENUM for the foreign machine, or it just dumps all sorts of extra detections into the existing ENUM tree. Older OSes don't take kindly to such an experiment. The worst case result of booting the wrong disk on a machine, is the OS "freezes" as a kind of punishment. Windows 10 seems more forgiving. Windows 10 had the option of Windows To Go, where the OS was placed on a USB stick and could be booted on more than one machine. That's been discontinued in the latest version of the OS, but you can still find various ways of doing it. Such an OS would need facilities to handle more than one machine as its host. Paul |

Win10 boot problems swapping HDDs

wrote: When you install Windows, it selects and installs drivers to suit your hardware, so unless the two machines are identical you'll likely have problems - it may not recognise your graphics adapter, for example, which would stop everything! Win10 is quite clever. I've used an existing boot drive to boot when I've upgraded my PC, including replacing the m'board and CPU, and, if the internet is connected, it just goes away and gets any drivers that it needs. Most of them will already be on the system out of reach and in case of need anyway. Having booted with new components the OS does then ask for proof of entitlement to a license, of course. Check the device manager to see if there are any components not recognised. |

I just need it to either work or fail so I can debug if the mabybad machine is a hardware or Microsoft problem. But both disks failed to boot when put into the opposite machine, which didn't tell me anything useful. That's why I asked (1) Can you put a good Win10 boot disk in another machine and will it at least boot once without saying it needs to repair itself? What you might try is to install a utility to assess the SMART metrics of your disk which will give you an idea of the health of the disk. Did all that long ago. That's why I didn't ask how to repair the Win10 installation other than to ask the second question. (2) Can you put a maybebad Win10 boot disk into a good machine so that you can repair the maybebad Win10 installation with an ISO file on the good machine? You might simply reinstall. Download the media creation tool from he https://www.microsoft.com/en-gb/soft...load/windows10 I did all that so I have the latest ISO on both machines' HDD boot drive and also on a DVD disc. The maybebad machine boots perfectly only one out of fifty times, and when it boots perfectly, it doesn't stay alive for too long, maybe 10 minutes, maybe a half hour, maybe even two hours but it WILL die with a light blue screen hardware exception error so I can't risk the Win10 ISO repair from the mabybe bad machine. To be clear, I think it's the Windows installation only if it's not the hardware since the mabyebad HDD boot drive works just fine installed as a second HDD in the good machine, I already ran diagnostics such as CrystalDiskInfo which says the drive is good. [https://downloads.tomsguide.com/Crys...13-25941.html] [https://fossbytes.com/repair-corrupt...ive-fix-disk/] I got similar good HDD results from AOMEI Partition Assistant Standard Edition 8.5 which I found by looking here for corruption diagnosis. [https://www.disk-partition.com/free-...-manager.html] [https://www.disk-partition.com/artic...cmd-7201.html] Aomei ran the checkdisk with repair but found nothing as I had already run chkdsk D: /F /X /R (fix, dismount & recover sectors) I even had Aomei repair the MBR but that didn't change anything. I had also run sfc a few ways but it keeps giving me the same error even when the maybebad HDD is a second disk in the good machine. sfc /scannow /offbootdir=D:\ offwindir=D:\windows "Windows Resource Protection could not perform the requested operation" And I had already set this in response to that error but it didn't work. IACLS D:\windows\winsxs It's not easy to boot the maybe bad machine to run it in safe mode because it boots perfectly only one out of very many tries (a few hours of work). I've already backed up the data from the maybebad machine to the good machine so I can format the HDD but the problem is more likely to be hardware I think since nine times out of ten the hardware won't recognize the HDD no matter which of the 6 SATA ports I plug the data line into. I think it most likely that there is nothing wrong with the mabyebad HDD simply because even the good HDD wouldn't boot in the maybebad machine. Both machines are older BIOS (not EIFI) where the boot order in the BIOS is correct. What is bothersome is that the built in HP hardware tests all passed where the built-in HP diagnostics passed the CPU, memory, and HDD boot path. It's flaky which is why I asked the two questions that I can't find an answer on the net for. (1) Can you put a good Win10 boot disk in another machine and will it at least boot once without saying it needs to repair itself? (2) Can you put a maybebad Win10 boot disk into a good machine so that you can repair the maybebad Win10 installation with an ISO file on the good machine? Because both failed and I don't know if they failed because they had no chance. |

I didn't know if that was due to Microsoft or the machines because I had expected at least the good boot disk to boot in the maybebad machine but neither did the mabybe bad boot disk in the good machine. I can't seem to boot off the external USB based optical drive on the mabyebad machine because it "says" it is booting off the optical drive with the Win10 iso disc loaded but it just stays black forever (its a very old 8x8 Sony optical drive as I haven't needed an external drive since forever). That's why I asked the two questions. (1) Can you put a good Win10 boot disk in another machine and will it at least boot once without saying it needs to repair itself?

The first CD-only drives (no DVD laser), those can't read "burned" discs. They would be particularly bad with CD-RW. I have several of those drives, which are about as valuable to me as boat anchors. The second kind of CD drive, used a higher power light source, and it can read a CD-RW. My MSI CR52 is like that. Then we move to CD/DVD drives, which have two lasers, and read most media. Bluray drives have three lasers, and optics differ for each path. Those read three disc types. You would think a USB optical solution, would at least have the second kind of CD drive in it. Unless this is an enclosure you assembled yourself, in which case any old drive could be installed. I use my own enclosure for optical drives, if I need a portable. I don't use a slim. ******* Booting computers has its moments: 1) 440BX refuses to use a DVD drive. The only test media you can use is CDs. The 440BX also won't boot from USB. And it won't use a SATA card. It will refuse. I use the CR52 and burned CDRW for that case, or install something on an IDE HDD and insert that. For example, I can install Linux on another machine, then bring the HDD over to the year 2000 machine and boot it. Maybe Puppy would work. 2) My P4B is more accepting of optical drives. But still won't boot from USB. 3) My P4C800-E Deluxe (P4 based) will boot from USB. Anything more modern than that (year 2005 or so), might also do so. 4) Super modern machines can be UEFI/CSM or UEFI or UEFI with Secure Boot. Secure Boot can cause problems for a tester, so ascertaining whether Secure Boot is involved, would be an early step in testing. You turn that off, before getting out your kit bag of discs and such. CSM is a legacy BIOS module, so behaves like an old BIOS. UEFI is newer, and more of a nuisance. Using the popup boot key and the popup menu, you can select one mode or the other. But there are exceptions, where the equipment and its popup boot, don't work right. If I have several USB devices plugged into the Optiplex, there is no control to select which USB to use, which means I can only plug in one USB at boot time. ******* Windows 10 can be placed on a USB stick. MediaCreationTool1903.exe could do that for you, amongst others. Sometimes, recent Microsoft images are hybrids, but they're not hybrids exactly the same way as the Linux ones. I've had optical discs, where the UEFI part is missing (and I might need that for GPT disk work). If you use the MicrosoftStore utility, it botches the UEFI part, whereas the MediaCreationTool seems to be OK for hybrids. A hybrid can boot UEFI or CSM, from the popup boot menu (two menu entries on a UEFI/CSM machine). The disktype.exe utility can be used to review optical media (as ISO or as a physical drive situation). I use a Cygwin version of that, for work in Windows. There is no port as a direct Win32 executable, but the Cygwin version works well enough. http://disktype.sourceforge.net/ Even in Windows, to have it analyze the partitions on a HDD, you use disktype.exe /dev/sda to pick the first row of what is in Disk Management, for testing. ******* Using onion skin test methods, you "prove" it's a computer as you go along. 1) memtest from memtest.org . Verify RAM is good, pass counter = 1. 2) Prime95 torture test from mersenne.org/downloads. Four hours error free is a good start. (Shortest failure time for me was three seconds.) This proves the CPU and memory are good. 3) On storage, the problem could be a defective SATA cable (if the SATA data cable is bent until it kinks, that damages the dielectric). The drive could be bad. Or the SATA power or data plug could be bad. There were some SATA power plugs that shorted out and burned, a few years back. That will spoil your day. Get the Seagate or WDC disk test diagnostics. The MSDOS one will be pretty worthless (probably won't boot on modern hardware). Only a P4 or older machine is a good bet for the MSDOS version. For the Windows version, you'll need to use a known-working PC to run the test of the defective drive. The test programs run the drive internal "short" or "long" SMART test. While on the Technician machine, you can also read out the SMART stats table with HDTune. Run the read benchmark and verify the HDD shows the normal "downward curve" for the transfer speed (outer to inner diameter). This program won't test large disks properly - 2TB is a comfortable max. http://www.hdtune.com/files/hdtune_255.exe 4) You could test the SATA interface on the Southbridge of the broken machine, using a golden good hard drive you use for such testing. Using your scratch drive, you can do a Clean Install to prove out the system, making it easier to test the NIC and so on. 5) A lot of boot problems with drives, only require "boot repair". For example, the other day, I got some complaint about "winload.exe" and the boot stopped. That was a BCD file in need of a refresh. Using a Macrium ReflectFree rescue disc, I used the boot repair and *only* ticked the "fix BCD" box. That's because the disk was a multiboot, and I have to be careful not to screw up the other materials on the drive. There are four tick boxes, if you want to repair everything offered. Making a new BCD in Command Prompt, is around four commands. That's how lazy I am :-) Eventually, you might discover there really are files missing. On some, the System Reserved might be marked with the Boot Flag. Well, say by some accident, System Reserved, the partition is removed. Now you've lost all the boot-related materials. That's not going to be easy to put back. There is a recipe for combining partitions, such that the boot materials all stay on C: , but this also reduces your recovery options. 6) If you're doing SFC or DISM offline commands, well, what's the point ? If that much damage has been done, I have to question whether the thing can ever be put exactly right that way. Maybe you have invisible registry damage too ? I would be looking for my backups, or looking to the system for backup versions to use for recovery of the Registry. 7) Repair Install is only possible from a running C: . If C: won't run, you can't do that. 8) You can back up the files by cloning onto a second disk. Then do a Clean Install. Then use a $50 version of Laplink, Easeus, or Zinstall, to move the programs and user data from the old drive, onto the now-running Clean Install C: partition. Or, you can do piece-meal movement of email databases, programs and user data, your own self. A person who repairs computers for a living, takes all sorts of shortcuts, as "time is money" for them. But by doing that, they're leaving it to their customer to do further testing, to determine whether there is still a problem. If you give me a computer, I go back to basics and do Step (1). The main reason I insist on starting at step (1), is because no one else may have ever done Step (1), and some issues were entirely missed by the owner. For example, I bought a brand new computer, for maybe $1500 or so. As a gift. Well, guess what. Step (1) failed. Bad RAM. Took it back. They put bad RAM in it a second time (different sticks). Never underestimate the value of testing. (I also had to teach the "tech" at that store, what memtest was!) http://www.memtest.org/ # Downloads, 50% down the page You'll need your Technician machine, to aid in this testing process (because the broken machine might not be obliging).

They would be particularly bad with CD-RW. I have several of those drives, which are about as valuable to me as boat anchors. cd-rw is less reflective and can sometimes be a problem with very old drives, but that hasn't been an issue for a couple of decades. |
