I tryed dual booting linux/xp together, worst mistake of my life.

Xp is the original os

And when I installed ubuntu from cd it autoinstalled grub. Grub updates ur mbr (master boot record) and now I can't boot into xp. I can only boot into ubùntu. My hdd is partitined to

440gb XP - 60gb Ubuntu. (500gb drive)

Since I can only go into ubuntu now...
I went on the ubuntu help forums and asked many times and no one will help me they all suggest things that have made the problem even worse. One person told me to download a program called "GParted" its a program that does partitioning and make sure ur drives are all well and good.. He told me to unmount my drive so I could use the program to check it... I unmounted it and now I can't even view my files anymore from ubuntu... (The windows partition files are still viewable from ubuntu but now I can't view). I can't mount it anymore because it has errors or something and it said my drive is unrecognised...

It started from as soon as I dual booted and when I press xp in the grub it says "Disk read error press ctrl alt del"

And now since I unmounted the drive it says something like

MBR: 12457

Or some number like that...

I reallyt need my pc to work again and I can only work this out using ubuntu -_- and for some reason my pc won't boot from cd so the most obvious option is gone... I can however boot from usb but I'm not sure about how...

Please help

Bump. Please all help would be helpful

anything on your hd you cant live without?

try formatting your Hd and just going with either XP or ubuntu.

my guess

I need everything on there...

Thousands of dollars of designing programs

Whole cs4 and cs5 premium suites...

And I have no cd's anymore to install it back... It was .iso

And all my movies and things /: I need alternative

which OS did you install first.

XP

If you can view explorer/see your files, you should just be able to back em up onto an external and then reformat.

I recommend reading how to use GRUB - http://www.gnu.org/software/grub/manual/grub.html

cant see my files.. my xp drive is unmounted -_-

and i still need help :/

unfortunately reading the grub documentation will not help me with my current problem....

yes it will

Well it is a big gigantic confusing page... im looking for assistance.. im really not going to find anything in that...

please just tell me how to do this... i really need help [sm-disbelief]

put your HDD(s) in another computer or connect them externally, buy a big external HDD, put everything on there, reformat your internal HDD(s), install XP (or Win7 as it is 2G) and put all your files back, tadaaa!

Only problem I see coming from that is that the programs will no longer work due to the lack of registry files, can't you re-download the .iso? Don't you still have the keys or something?

try installing upuntu first instead of XP [sm-disbelief]. Not sure if it will work though.

XP then linux, it will then use the grub boot loader. how you managed to **** that up I don't know.
