Right now I have two hard drives with Windows 7 on one. I'd like to put Windows 8 pro upgrade on the other drive. I have a few older versions of Windows Vista oem.
Can I start the computer with the vista install disc in the dvd drive and install to the second drive?
Then install Windows 8 over it (Vista) and be able to not mess up my Windows 7?
1. Partition the disk. On a single disk PC, you will need to partition the disk first. (If you have two hard disks attached to the PC and wish to use the second drive for Windows 8, you can skip this step.)
disconnect the hard drive with windows 7 on it first
then reconnect it once you are done
this keeps your windows 7 being included in the boot record
then just select which drive to boot either in the bios or by pressing the appropriate f key to bring up your boot menu
Thanks mcnumpty23, Your advice was exactly what I was thinking to be sure w7 didn't and couldn't get messed up.
Well it was a success. Everything went smooth. Installed vista then Win 8 pro. Hooked up my Win 7 drive and crossed my fingers. At first it loaded the Win 8 but then showed the boot options.
