How can I repair grub? (How to get Ubuntu back after installing Windows?)
Recently i bought a lenovo u410 ultrabook. It has given along with windows 7 and 4 primary partitions. So to install ubuntu 12.04 i removed one of the primary partition and made it as extended partition. In that extended partition, i allocated memory for the swap and root (/) directory and then installed the ubuntu. After that by using EasyBCD tool, added ubuntu to the boot menu in grub2. So when i try to boot into ubuntu it is showing grub> prompt only. From there how can i boot into ubuntu.
Thanks in advance
UEFI
... Please if possible, look inBIOS
if there's is an option to switch fromUEFI
toBIOS legacy
or something similar. I had the same problem on myAcer
laptop. This option should be available in the same place where you choose the boot order.
