I have a new ASUS G752VL-DH71 laptop. I would like to make a backup of the current installation of Windows 10 in the form of a virtual hard disk file (VHDX) and I would like to be able to boot into that VHDX file. This is because I plan to reinstall Windows 10 but I want to keep the old installation around for reference. This topic was discussed recently on Channel 9.
When I try to boot to the VHDX file, I just get a blue screen of death that says INACCESSIBLE_BOOT_DEVICE. Can anyone tell me how to fix this error? If not, could you please tell me how I can debug the error?
Details about what I did
I ran Disk2vhd 2.01 to convert my main partition into a VHDX file. Here is a screenshot of what Disk2vhd looks like when I run it:
Notice how there is no SYSTEM partition shown. The video on Channel 9 showed a SYSTEM partition in Disk2vhd, but on my computer Disk2vhd does not show the SYSTEM partition.
I know that I do have a SYSTEM partition because when I run
diskpart in a Command Prompt and run the
list volume command, the output is:
Volume ### Ltr Label Fs Type Size Status Info ---------- --- ----------- ----- ---------- ------- --------- -------- Volume 0 D DVD-ROM 0 B No Media Volume 1 C OS NTFS Partition 930 GB Healthy Boot Volume 2 SYSTEM FAT32 Partition 260 MB Healthy System Volume 3 RECOVERY NTFS Partition 499 MB Healthy Hidden Volume 4 G SSD NTFS Partition 476 GB Healthy
I can also see the SYSTEM partition in the Disk Management snap-in.
If someone could tell me why Disk2vhd does not see my system partition and what to do about it, then that would probably solve my problem.
In Disk2vhd, I tried selecting the main partition (C:) and the RECOVERY partition, and leaving both checkboxes checked (Use Vhdx and Use Volume Shadow Copy). I also tried not selecting the recovery partition. Both selections had the same effect; giving me the blue screen of death mentioned above.
