tulungaq · January 2015

hallo.

im joining this, hoping tbat anyone would help me to fix this problem.

I dual booted windows 7 and debian wheezy, I wanted to boot windows 7 first, but, only windows boot (no option to choose debian) so I did boot to rescue mode to fix this, and fix this /etc/default/grub and change thjs GRUB_DEFAUlT=0 which debian but only to boot debian.

and did this with grub terminal on boot changing the (hd0,msdos6) to (/dev/sda6 and I cannot change this again cause I cannot open it/boot to.

how do o fix this?

Cant seem to delete this

Managed to fix this though, i had set boot time to zero.

had to reinstall debian

Are you still experiencing the problem?

You don't think to need to use /dev/sda6 to indicate the root device of your installation. GRub2 seems to read hard drives using dos-type naming, e.g, (hd0, msdos6) which would represent /dev/sda6.

I am not very fluent using the grub-rescue image. I find it much easier for me to use a startup-disk.

If you are unable to boot your system, boot your system using a LiveCD and run gparted. Notice the partitions that have windows and debian installed and the names of the devices they are installed on. Then navigate to the /boot/grub/grub.cfg file and rename the "root" devices of your OS installations as (hd0,msdosx) = with "x" representing the number of the partition the OS is installed on.

Use this entry in my grub.cfg file as a guide.
