I booted up my computer and got the message
I share my computer with my brother and he deleted the main partition linux was on trying to get rid of it and get extra space for the windows partition. Is it possible to boot to windows from the grub rescue? and if so how can I correctly uninstall the rest of linux and clean up my bro's mess? If not what do I need to do to be able to boot to windows?

Use your windows installation CD to repair the bootloader. Grub has part of its files in the master boot record but most of them were on the partition your brother deleted making your system unbootable. You don't indicate which version of windows you are using so can't give more specific instructions.

I have a compaq presario c500 with windows 7 installed on it.

If you don't have a windows 7 installation CD or a recovery CD, you can download a recovery CD from this site:

I'd suggest you read the instructions before beginning.

I wanted to say thanks to Miros84 for their reply about grub rescue errors. The link provided was so easy and fast. It fixed my computer in nothing flat

grub rescue>root=(hd0,x) ##set / partion
grub rescue>prefix=/boot/grub
grub rescue>insmod normal
rescue>normal

This had happened to me when I installed Ubuntu 12.04 from my usbdrive. I found out that the GRUB had been installed on the USBDrive, so I reinstalled it into the harddisk. First find out your harddisk's name by:

There will be a list of something like sda1, sda2, sda3... In this case the HD's name is sda. So you will have to install GRUB in sda. To do this, do this:

This should work (it did for me).

hii every1,
I am new to linux. I had windows 7 installed in my laptop. Yesterday i installed ubuntu9.0 from a free cd i got. I choosed the option "install side by side with windows7 loader(something like that..)". everything went fine & i installed ubuntu. When i restarted my laptop, i couuld easily boot from both windows 7 loader & ubuntu.
But later when i booted from windows 7, i did a disk management by right clicking "my Computer" & choosing the option "Manage". Actually i deleted a drive & added that empty volume in another drive.
Now when i start my system it shows the following error:
Grub loading
Unknown file system
grub rescue>
====
I have no clue what to do now. please help me at urgent.
Any solution in layman's language is greatly appreciated.
Thanks in advance
P.S- I want all my files(no data loss)& both windows 7 & ubuntu installed.

9.0 is definately an outdated & unsupported version, you will be better off with a more current version.

Since you were able to boot windows you may be able to install an upto-date version of Ubuntu, but, I suggest that you backup your data first. You also have the option of repairing windows with a windows installation disk.

In the future open a new thread instead of reviving an old thread.
Good luck.

Thanks for the prompt reply Eddy
Actually i thought once i install it, i will do an update. And maybe u misunderstood..actally now i cant boot either from windows or from ubuntu. When i start my system i get the error mentioned "unknown file system grub rescue"
And i installed 9.10. I mistyped it as 9.0

You were able to start both.
After deleting from a partition from windows you can't boot either os.

Was the Ubuntu a desktop version? If so you can boot it & select Try Ubuntu which will let you mount your partitions & the tools that are on th live-cd.
Most likely you deleted the / partition hat contained your grub.

some one help me i got same problem Please

Ubuntu 9 is outdated install the newer version & you should be fine. You most likely deleted 1 of your linux partitions.
