OK, this is weird. I was trying to dual boot... Windows Vista 64 and XP pro 32bit....
But instead of getting the OS choice menu in boot up - I Now have realized that if i unplug one of my external eSATA drives the computer starts up to XP Pro but if I plug the drive in and restart it boots up to VISTA. What? This is a non system disk and should have nothing to do with it.
Here is the story...
So - On a single disk, I had two partitions for a dual boot. Both with Windows XP Pro 32bit installed on The C:/ Drive and the D:/ drive. --( This on a Raptor 150g drive split down to two 75g partitions.)
I decided to upgrade the D:/ drive partition to Windows Vista 64bit while wanting to maintain the C:/ drive with WinXP pro and all my old 32 bit programs and settings.
So I installed from boot. I did this and selected the D:/ drive from the list of drives to install Vista to - and overwrite the existing XP partition on the disk.
After install - I assumed i would get a dual boot menu to be able to choose Windows XP pro or Vista 64 -- But instead - it goes right into Vista. 🙁
From Vista - I went to my computer and I see the drives letters are now changed... What was the C:/ drive partition with WinXP is now the F:/ drive partition. -And what was the D:/ in XP is now the C:/ drive with Vista.
I need the dual boot to work.
From Vista i went to DISK MANAGEMENT - and i see that one of my backup storage Hard drives (non system) (750g) is set as Active. Thus, it will not let me change drive letters. If i shut down the computer and unplug this Active drive then restart the computer - the system boots into Windows XP now. - No mention of VISTA.
