I have a Dell Inspiron laptop which was set up to dual boot windows Vista and Ubuntu 10.04.
I created a live USB image for Ubuntu 10.04 using Unet bootin and rebooted from from this to install Ubuntu on an SD card.
When I remove the SD card and reboot the laptop I no longer get the GRUB loader menu, instead I get the “GRUB error” message.
I can not now boot into Windows Vista or Ubuntu!
Obviously I have caused a GRUB error.
I have rebooted using the USB live image and run fdisk –l and blkid, the outputs are listed below.
Can anybody tell me how I can restore the GRUB loader menu back please so that I can access Ubuntu or Vista?
