Am experimenting with different ways of multi-booting my tablet PC. I have three OSs installed (in the following order): Vista, Win 7 RC, Ubuntu 8.04. I had previously set this up with GRUB installed to the MBR and used the menu.lst file to select the OSs. Yesterday, when trying to boot into Win7 got an error message of no operating system found! So, last night, restored Win 7 boot from the Win 7 DVD -- which, of course, overwrote the MBR. So, I used the SuperGRUB disk to restore GRUB to the MBR and I can boot OK now. But, every time I get a Vista or 7 problem, I have to go through this reloading GRUB each time, and I thought I'd try using EasyBCD -- since I'm planning on migrating to Windows 7 nearly full-time. So, I installed Beta 2 Build 63 (which I what I had downloaded a while back), went into EasyBCD, and added Ubuntu as a boot selection from the Linux tab. But when I choose that, the screen blinks for an instant and returns me to the boot menu. So, this morning, I downloaded and installed EasyBCD Beta2 build 65 -- and did the same thing again. Same results. So, I used the Ubuntu LiveCD to install GRUB to the Ubuntu partition. And tried again, thinking, that maybe if GRUB is there, the menu option would work. I tried two different options -- with and without the GRUB is installed to the MBR box checked -- no success either way. I'd like eventually to just use EasyBCD and leave the MBR alone but if I use the Win7 DVD and restore the MBR, without EasyBCD working, I would lose all access to Ubuntu (which I need for the short term), and would only have to go through the restoring GRUB to the MBR stuff again. So, I'm puzzled what to do next. Any ideas?
