Grub 2 Error Booting Windows:
1 2 3 4 | Error: Invalid Signature press any key to continue... |
Solution
Step-1: Find UUID by running the command:
1 2 3 | $ sudo blkid |
1 2 3 4 5 6 | /dev/sda1: UUID="6b37e778-0fd6-470f-b65b-4f922e720b42" TYPE="ext4" /dev/sda5: UUID="7a721379-43f5-4752-9a46-f0f9f3fa14e3" TYPE="swap" /dev/sda6: UUID="73f63f9c-bfe2-4d85-a7fb-557a19617884" TYPE="ext4" /dev/sdb1: LABEL="iSHY-EHDD" UUID="687D0AAA333A2C12" TYPE="ntfs" |
Step-2: Edit 40_custom grub file:
1 2 3 | $ sudo vi /etc/grub/40_custom |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | #!/bin/sh exec tail -n +3 $0 # This file provides an easy way to add custom menu entries. Simply type the # menu entries you want to add after this comment. Be careful not to change # the 'exec tail' line above. menuentry "Windows 8" { insmod ntfs set root=(hd0,1) search --no-floppy --fs-uuid --set 687D0AAA333A2C12 chainloader +1 } |
It would boot from the /dev/sdb1 drive.
Step-3: It will add the new entry in the grub.
1 2 3 4 | $ sudo grub-mkconfig $ sudo update-grub2 |
