Bootloaders?

by Ski_rus12 / January 17, 2010 10:59 AM PST

I currently have 3 partitions in use. One with Vista installed, One with Ubuntu installed, And the other with just a few files. The Bootloader I am using is GRUB, It replaced the Vista bootloader when I installed Ubuntu. Soon, I will be upgrading to Windows 7. Before I do, I would like to know what will happen to my bootloaders when I do.

I expect one of the following:

1. The Windows 7 Bootloader will overwrite GRUB and I will not be able to access Ubuntu OS.
2. The GRUB bootloader will remain and I will not be able to access Windows 7
3. The GRUB Bootloader will remain and I will be able to access both OS.
4. The whole thing will stuff up and I won't be able to access either OS.

Which one of these is most likely, and what should I do to make sure everything runs smoothly? I don't mind If I loose the Ubuntu Install, It's an old build now anyway.

Thanks. Wink

It'll be #1

It'll be #1, but you should be able to boot off the Ubuntu install DVD and then use that to reinstall GRUB. I wouldn't anticipate any problems with GRUB booting Win7, since it can boot Vista and 7 is really a minor update to Vista, but it couldn't hurt to look around a bit beforehand to find out for sure.

Thought So

But instead of just reformatting the Windows partition. I thought I might use GPartred Live CD and reformat the entire hard drive, delete the partitions, and re-partition it how I want it. Then Install Windows 7, Then Ubuntu and use the GRUB Bootloader again.

Sounds like a longer way around it, but it would mean a more complete fresh start. Especially as one of the Partitions is 100gb and I'm only using about 2gb of that partition.

I'm quite sure that GRUB can boot windows 7.
Thanks for the info Wink

In this case...

It's really not applicable. If XP is installed first and Windows 7 installed second, 7 will automatically detect/add XP--actually, a 'legacy' entry referring to boot.ini--to the BCD store. On the other hand, if XP is installed second, 7 will fail to boot, and XP is not natively capable of modifying the BCD store, something it doesn't recognize. For those dual-booting multiple copies of Vista/7, or those who want to make manual changes after the fact, though, it's a good guide.
