I was currently dual booting XP and Vista on same disk and decided to triple boot Windows 7 on same disk. After installing Windows 7 (from a USB pen drive) and rebooting, it did not show up in Boot Manager so I did a repair from the Windows 7 install drive then got a bootmgr missing message. I fixed this by booting from the Vista install disk and repairing and managed to get Vista to boot but noticed that the boot manager entry for XP was missing. I added the entry for it in EasyBCD but when I try to boot into XP the computer restarts. Advice greatfully accepted and has anybody managed to triple boot these?
Addendum:
Solved the XP not booting bit. It's been a while since I set up the dual boot originally and was setting XP as drive D: (ie using easyBCD in vista and that's the drive partition it's on), but it needs to be set as drive C: because that's where Boot Manager looks when the computer is booting up. Silly me. I could use advice on why Windows 7 does not appear in Boot Manager as it uses same loader as Vista? Is there anyway to force it using easyBCD?
Addendum:
OK, I did another Windows 7 install to the same partition as before and I can triple boot. It must have been a bad install before? The only difference is this time I installed from DVD. Windows 7 installed a "Earlier version of Windows" . This is XP. Since there was already an entry for XP from the dual boot, I deleted that entry and kept the Windows 7 one.
