Corrupted grub after upgrade to 11.04

[xilod]

Hello everyone!

Yesterday all my troubles seemed so far away, because I've been using working system with Windows 7 & Ubuntu 10.10, but last night I decided to update to 11.04 from update manager. So, when upgrade was done, I rebooted and saw something like this:
"grub_env_export not found
grub rescue > "

Do I have a problem with MBR? Will it help, if I load from Ubuntu live cd and try to reinstall grub? If so, how can I do it correctly(I'm quite new to Ubuntu and Linux)?

Thanx a lot

Thank you, but I've already found a solution, it was as follows:

Booted from Ubuntu Live CD and reinstalled GRUB(and wiped out 32d sector where GRUB saw FlexNet) then I had GRUB worked, but Win 7 couldn't load. So I booted from CD with Win 7 distr, where I choose Repair System->Command Line-> Bootrec.exe /FixBoot

And now everything works!
