Ok, so, I've finally decided to try and get this 25 GB unallocated partition back to regular space. Problem is, I'm afraid to try and do it, because I can make my computer unboot-able in the process. I believe I can always get it back by using my Ubuntu Live CD and reinstalling GRUB over whatever junk my boot sector might have in it after I try this.

I plan on getting rid of my Ubuntu 9.04 partition (all 10 GB ), and recombining that and the other 25 GB of unallocated space with my Vista partition.

Basically, I just want to get the Vista bootloader back, so that I can get rid of partitions without making my bootloader freak out.

I plan on backing all of my data up, as soon as I get an external hard drive, which shouldn't be too much longer.

So, how can I get my Vista bootloader back? I'd like to NOT have to use my HP recovery DVDs. As far as I know, there's no option on those to do anything but reinstall the entire operating system and everything that came with it. I know my recovery partition has a console option that I've used to recover my bootloader before, but my recovery partition is corrupted.

Actually, on second thought, backing everything up and just reinstalling everything sounds like a decent idea. Then I'll have my recovery partition back and everything. And have a clean system with all of my files on an external hard drive.

What do you guys think?

IDK, I did this a while ago, I (ignorantly) deleted my Ubuntu partition which killed my vista loader and rendered my computer unbootable past the "grub 1.5 loading" or whatever it displays. I had to hunt down some vista discs to get into CMD.

I did this:
Boot into CMD
type bootrec.exe

If that does not work, you can export and delete the BCD and than run the option again. To do this use the following commands:
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd

options to go along with this are:
/FixMBR Fix master boot record, use this option when you must resolve MBR issues or whan you have to remove non-standard code from the MBR

/FixBoot this option writes a new boot sector to the system partition that is compatible with vista. Use this option if the following are true:
1) boot sector has been replaced with a non-standard vista boot sector?
2)boot sector is damaged?
3) earlier version of windows has been installed after vista, causing Windows NT Loader (NTLDR) to be used instead of Windows Boot Manage(Bootmgr.exe)
