I've on my PC win7 64bit and I installed ubuntu 12.04.2 LTS 64bit yesterday. I used to prepare bootloader via EasyBCD (I prefer BCD instead of GRUB as main bootloader).
In installation process of ubuntu I set that GRUB will be installed at /dev/sdb5. Everything was ok, after first reboot I was able to choose Ubuntu on my BCD and GRUB started, Ubuntu loaded and everything was ok. First thing I did was to update my ubuntu, and after that, when I choose Ubuntu from my BCD I only get text "GRUB" on black screen, and nothing happens.
Is there any possibility to fix this? (I can't get to my ubuntu) Or I have to reinstall ubuntu, but this time with update while install (I always uncheck this option in installer so I'd rather to update ubuntu manualy after install).
Sorry for my english, I'm trying my best
