hi i am new to Linux and i just installed SUSE 11.1
Im dual booting it with vista and it works but it makes vista really slow on start up.but my main problem is that i want to use the vista boot loader thing(the one u choose to boot with vista,xp or Linux)instead of the SUSE one and make vista the default.
Having said that. There is no reason why using grub should cause Vista to run slowly.
Have you changed any settings in Vista related to virtual memory (pagefile)?
Edit: Caution. To changing the Boot order in Yast as suggested by @Akoellh. Unless you are Updated fully, don’t do it!! Update Suse fully first. There was a bug in the release which can cause you to screw up the bootloader. Once updated - fine
