Can Windows 10 technical preview be dual booted?
I have a spare 128 Gig SSD that I can put it on just to try. I don't want to disturb my Win 8.1 setup on my primary SSD Regards, Rene |

I don't want to disturb my Win 8.1 setup on my primary SSD Regards, Rene I used a blank 500GB drive, for the Win 10 install. There were no other disks present during the install. After it is installed, I can plug the other OS drives back in, but I haven't done that yet. ******* If dual booting, I recommend opening a command prompt as Administrator. (Start : "cmd.exe" : right click and Run As Administrator). In there, enter this. This would be for Win8 or later systems. powercfg -h off That turns off hibernation. That is to prevent the OSes from using kernel hibernation, so when you select "reboot" from Windows 10, the BIOS will allow you to select some other drive to boot from. Otherwise, the hibernate bit is set, and a chance to select a boot drive is disabled by the BIOS. You will stay "trapped in a loop" booting Windows 10, until you can figure out how to "do a complete shutdown". I just turn off hibernation, so it will not be able to annoy me any more. ******* In terms of side effects, of modern OSes being next to one another, you may get spurious "CHKDSK" runs at startup. That's where the file system doesn't seem to be shut down cleanly, from one OS run, to the other one running. Since I only ran the Win 10 preview for five minutes, there wasn't much time for testing old bugs. My evidence here, seemed to suggest the Win7 Preview OS was spinning down one of the disks, and the CHKDSK was related to doing an OS shutdown when a disk was no longer spinning. But others here don[t feel that is the root cause, and I still don[t really know what made it stop. I messed around with Power Options a fair bit, so just about anything might have fixed it. I was more interested in making the symptoms go away, than anything else :-) If you see other aberrations, Microsoft is pretty good about including bad drivers with their install media. It's the fault of the hardware manufacturer, for not making good drivers, and Microsoft's fault for not testing the drivers properly. I've had three cases now, traceable to bad drivers on the install media. This probably won't damage anything, but could make the preview behave badly. I've had 1) Flashing screen due to video card restart. Not fixable. No better driver available. 2) Sound output that would "thump" at startup. Fixed by a driver update. 3) A video card bug where only half of the dual head stuff was working. A driver update fixed that one. Hardware acceleration on the second half of the video card is disabled, so that if you play a game and alt-tab out of the game, the remaining half of the card no longer is hardware accelerated. Screen redraws are very slow. Paul |

No formatting or boot manager upset, just uninstall the VM software and delete the data files they create. A bit more simple. |

Thanks Paul, I did turn off hibernation as you suggested and the whole download and install proceedure went without a hitch. To Mechanic, I do these things because all my life I have been curiouse and want to know and learn about everything. so I am in the habit of bending things till they nearly break :-)) Ferinstance the other day I was trying to eradicate the Snap do rootkit from my sons PC, In so doing I was checking and deleteing stuff from the registry of my own PC which is clean and running fine. Anyway I mucked around till I finaly bluescreened it and Windows complained and shut the system down. First shutdown in 4 years on this machine. By the way I am 80 years old and need to speed up my activities as time is running out. Regards, Rene |

Tap tap tap Google - Wow, I didn't know hibernation didn't first dismount and then reload the disks, thanks a lot for the warning! SuperUser had this to say - If you want to hibernate and use a different OS while Windows is hibernated you must not put the Windows bootloader first, contrary to what @snayob says. If the Windows bootloader is first, the very first thing it does before showing the menu is check for a hibernated OS. If a hibernated OS is found, it will boot into it automatically and will not show you a menu to choose boot options from. If you force the menu (i.e. F8), the hibernation data will be deleted. Now if GRUB is the MBR boot menu and is configured to chainload BOOTMGR or boot into Linux, you can hibernate Windows and boot into Linux - but if you mount the NTFS partition, most likely your hibernation will be lost (detected as corrupted). Basically, if you hibernate a machine, you must not touch any volumes that were mounted on that machine (i.e. any FAT32 or NTFS partitions assigned a drive letter in the hibernated OS). Ridiculously important note: In the event that you mount (say, in Linux) a Windows partition while Windows is hibernated and you are unlucky enough that when you're done with Linux and attempt to reboot into Windows, Windows does resume from hibernation (instead of erroring out, throwing away hibernation data and attempting a normal boot), you will most likely suffer catastrophic data loss to all Windows partitions as all filesystem-related structures will be out-of-sync between what Windows has loaded in the memory and what's actually written on the disk. -- ! _\|/_ Sylvain / !
