I wanted to try the Vista beta on a fresh Virtual PC this evening, but setup doesn’t cooperate.
Here is how I worked around it:
When you get to the “Install Windows” screen, press Shift+F10 toopen a command prompt. Type DISKPART at the prompt and use the following commands.
select disk 0 create partition primary select volume 1 format fs=ntfs label="vista"
After this I typedEXIT to leave the utility, reset the VPC, and started the installation again.
If everything looks good, I’ll cross my fingers and install on my non-virtual laptop over the weekend.
