I am in the process of installing both Windows 7 Pro 32bit and 64bit as a dual boot on a new 120Gb SSD.
I installed a 32bit Windows on the SSD then partitioned the SSD and installed a 64bit copy with a clean install, and all went well, with no problems booting into either OS untill I installed the video driver
(Sapphire ATI HD 6770) on the 64bit OS (I didn't need to install a driver for the 32bit OS as it was already installed) after rebooting the 64bit OS it got past the Windows logo then just locked up (just a cursor that I could move around with the mouse).
I tried to reboot again to try and fix the problem but the 32bit OS booted with no dual boot choice sceen.
The problem I have is that I don't know how to get the dual boot choice screen back so that I can try and fix the problem on the 64bit OS, so I would appreciate some help please?
Once I can boot into both 32 & 64bit OS's I will try and fix the video problem myself and if not, ask for help again.
Thanks in advance for any and all help
