Hi I've got XP Pro 32 and decided it was time to go for Vista Ultimate 64. I made a new partition on my HD, XP is installed on the main partition, crap is stored on the second, and the third is the new one. So I start installing Vista and it all goes well, I get to the time and date setup wizard etc then when I go to log-in for the first time, the Vista logo pops up like normal then the PC reboots, gets passed post then gives me some text about 'Vista Bootloader 1.2.1' or something similar. It tries to boot but fails and has to resort to 'fallback 1' where it looks for 'bootmgr'.. and fails, so it tries fallback 2 to boot XP and that fails. I have now managed to get back onto XP after alot of grief (Had to install vista again and during one of the reboots it does I have to choose not to carry on with installation but to load older version of Windows.) I have tried to install 3 times now. If I boot from DVD it gets passed the boot screen and I get to a vista backdrop with a cursor, which after about 3 minutes turns into the first part of the installation wizard, woo! Has anyone encountered this before? Or know a way around it? I was thinking I might just buy a new HD, unplug my current one and install Vista on that from scratch, that should work, right? I can't afford to format my HD or I would. Any help greatly appreciated, thanks.
