Win7 in boot-loop. Help!
Hi, during the installation my new video card I didn't realize
that the sata cable was unplugged from my ssd (Samsung 850 Evo). My system have two hdd in raid 0 configuration and a 1Tb hdd. I tried to use the command bootrec.exe messing a bit until i realized that the cable was unplugged from ssd. When i re-plugged the ssd unit i have the system in boot-loop. My friend told me to use the command bootsec.exe /nt60 all and the system gave me this result: https://www.dropbox.com/s/bkiwx2tq5e...pgbr / ?dl=0 and restart e restore the system but i didn't fix the issue. Then i tried the following guide: http://www.sevenforums.com/tutorials...-recovery.html But when i see the content of Regback dir i don't find files and subdirectories. I tried to unplug all disks keeping ssd unit only, but i have the same issue How can I solve it? -- 'Za Fo'! ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

I tried to unplug all disks keeping ssd unit only, but i have the same issue How can I solve it? The problem the people here had, is no RAID driver in the recovery console. Something you might rectify by constructing a custom recovery CD. http://answers.microsoft.com/en-us/w...b-b27d426a6811 "I boot from dvd to Recovery Environment, operation systems list is empty. Press Load Drivers find AMD RAID drivers on motherboard drivers disk and successfully load it. But operation systems list is still empty. But when again press Load Drivers, I can see and explore my system disk, view folders and files! How to bring it to operation systems list? Without this recovery system is not work properly (for example registry access)." If I was sitting in front of the machine, one of my steps would be to enter the BIOS setup screen, press "control-I" or whatever the manual tells you is the hotkey sequence for the RAID setup screen, and review whether the SSD drive(s) status still says "RAID 0 array". Or whether the thing has reverted to two separate disks or something. That's a check to see if you could possibly have done any damage or not. A RAID0 stripe should really stop instantly, if the array status goes to FAILED. And it goes to FAILED, if the cable falls off either disk. There is no DEGRADED status for RAID0. You really shouldn't use RAID0 for C:. If you do want to operate that way, you should make *daily* backups of the C: partition, to your 1TB hard drive. Then you could do a restore and get yourself out of this mess. One piece of information you might get from the BIOS screen, is the block size of the interleave. The stripe alternates between drive 0 and drive 1, when it comes to actual storage. It might switch back and forth every 64KB or every 128KB, as examples of typical values. You can "de-interleave" the SSD contents, and transfer it to a regular hard drive, Then attempt to do maintenance or repair on the single hard drive, in AHCI mode. That would be a way of taking "RAID" out of the situation. This is why, when using RAID, it is important to write down critical details about the RAID setup. Like, which drive is Drive0 (has the MBR), which drive is Drive1, and what the block size of the interleave happens to be. That info is all recorded in the metadata, but if you need to triage the two SSDs on a foreign system, the metadata might not be accessible there. RAID is *not* recommended for home users. Period. And end of story. It's just too much work. Too much forward planning is required. Too many test cases to run, to prove you "deserve a RAID drivers license". It takes a lot of work, to be prepared for days like this. Buy an SSD which is twice as fast (on a desktop, this would be an SSD on PCI-Express card, rather than a SATA SSD). This is not practical on a laptop, but is an option for desktops. (Example of the concept... Much research required.) http://www.newegg.com/Product/Produc...9SIA4S81Z32403 Paul |

OK, so explain "what is a boot loop". You're seeing the system start booting, then stop at some point and restart, repeating the broken sequence all over again. What are the steps that you see on the screen ? ******* The Windows 7 DVD repair options, probably do as much as you can attempt to do by hand. This page has an extensive recipe, probably too extensive. https://neosmart.net/wiki/recovering...ws-bootloader/ You can probably run "bcdedit" from the Recovery Console. I assume when it asks to log into a particular C: partition, that's how bcdedit will know what BCD file contents to display. Paul |

Be very careful about which volume is which. Try out diskpart and "list volume" or something, and try and verify which item is which in there. That way, you may be able to issue the command to the correct storage device. OK, I can emulate this, using my Win7 VM. I have two physical Windows 7 installs right now, but they're single partition (no boot partition in a System Reserved). Only my VM has two partitions. Let's see what it's got. I will boot the Windows 7 installer DVD there, and ask it to log into the only C: present. http://i58.tinypic.com/2q3xki8.jpg X:\sources --- when I ran diskpart, this dir was the current dir E GRMCHPFRER --- This is the boot DVD C System Reserved --- This contains C:\Boot\BCD D Win7 --- This is the actual C: drive Once I exit diskpart, I try this C: dir and the thing is virtually empty. I have to do dir /A:H C: dir /A:H C:\Boot --- see the binary BCD file here in order to see C:\Boot contents. I don't understand at the moment, what the difference is between E: and X: . E: looks like the DVD itself. Whereas X: looks almost virtual, like a RAM Disk maybe ? I would not "createstore" on X:, I'd do it on C: which is System Reserved. On a two partition install {C:, System Reserved}, System Reserved is the one with the boot flag set on it. And that's where the first steps of booting vector to. Paul |

Only this unit!! So what do you conclude from this ? Severe file system damage ? Or the Recovery Console isn't mounting the volume for some reason (no driver) ? Perhaps it is time to get TestDisk on the job. And see if any files on the missing partitions, can be seen or not. TestDisk can be run from Windows or Linux. Since your WIndows is broken, you could use a Linux LiveCD perhaps. This scans for partitions, but also has an option to view the files on a partition (only possible if there isn't severe damage). The purpose of the tool is to recompute the partition table, but in this case, the file viewing part of the thing is what I'd want. http://www.cgsecurity.org/wiki/TestDisk There has to be some reason why DiskPart cannot see the material in question, right ? The Linux LiveCD should be able to view the partitions. If it cannot, then TestDisk can be used as the next step. Paul |

If you can see the drive with folders and files when booting to a Linux disk is good news. Now get a second external drive and try and copy everything from the original drive to it. Then test what that drive does when inserted back into original pc. Note : it may have more than one partition on it which complicates the procedure. You should check for that. Unsure how using Linux. Least that's what I'd be trying next My ssd has only one partition. You mean to copy everything in second hard disk and try to boot from it. At this point i can format the ssd and re-copy from hdd to ssd all thing. In this way could it work? -- 'Za Fo'! ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |
