Hi there. Before I installed Vista this morning I had 2 operating systems, using the XP boot menu, XP Professional and Fedora Core 3. After installing Vista, I wanted to carry on using this menu, so following instructions I found on the internet, I booted to the recovery console and ran fixmbr, fixboot etc. My boot.ini now looks like this: [boot loader] timeout=5 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn c:\fedora.mbr="Fedora Core 3 64 bit" multi(0)disk(0)rdisk(1)partition(3)\WINDOWS="Microsoft Windows Vista beta 1" /NOEXECUTE=OPTIN /FASTDETECT However when I select the Windows Vista option, all I get is a black screen and nothing happens (as though there is no bootable information) The relevant hard drives are partitioned as follows: Disk 0: NTFS Windows C: 76,322MB Unallocated space 7.8MB Disk 1: Unallocated space 7.8MB Extended Partition: 78,152MB - NTFS My Documents F: 30,718MB - EXT3 Fedora L: 32,130MB - NTFS Vista M: 13,311MB - SWAP Linux Swap 1,992MB Thanks for your help in advance, Mitch PS. I have tried Vista with and without the /USENEWMENU switch
