I have two computers both running 32bit Win7. Both are 64bit capable. Each PC has its own copy of Windows 7 Home Premium.
I have two HDDs' on each PC and want to install Win7 64bit on the second HDD and use a Dual boot facility. These D: drives have been formatted NFTS Primary.
Leaving Win7 32bit on the C: drive, I have installed Win7 64bit onto the D: drives on both machines. The 64bit has then activated with Microsoft.
When I begin to load down the updates from Microsoft I always (on both PCs and two or three separate installs) get an error note that says the install is corrupt.
Even using chkdsk /f does not fix the problem. Am I missing something obvious? Surely I can run both 32bit and 64bit on separate drives!
