BSOD upgrading from 7000 x86 to 7048 x86.
I started the upgrade and left the computer installing...
When I came back I saw a BSOD (0x0000007b (0x80786b68), 0xC0000034, 0x00000000, 0x00000000).
I restarted and saw 2 options (Windows SETUP and Windows 7).
Computer gone to Windows Setup again and showed BSOD again. So I restarted and got Windows 7 7000 again... (no changes made). I received a message saying that the upgrade couldn't be made and my original version was restored or something else...
I have no idea about the reason of the BSOD. Never had problems with 7000.
