Accidentally deleted partition

[robirahman]

I accidentally deleted the hard disk partition containing Ubuntu in Windows' Disk Manager, and now cannot boot either operating system. When I turn on the computer the following error is displayed:

error: no such partition.
grub rescue>

Does anyone know if it is possible to bypass GRUB and boot Windows? I can create a live CD if it helps. Thanks!

Use a live disk of ubuntu, install testdisk to that and you may be able to restore the partitions back to where they were before.

Whatever you do, do not install anything to the hard disk or do anything else with it other than attempting to restore the old partition table. If you do you could lose any chance you have of restoration.

PS: I've never used testdisk, but you can find info and more details at https://help.ubuntu.com/community/DataRecovery

ajgreeny's suggestion of testdisk is good if you want to recover Ubuntu.

If you just want to boot Windows :( , You just need to install a Windows or Windows like boot loader to the MBR.
