No Linux Mint entry on boot screen after installation[Solved

[sundar_ima]

Recently downloaded Linux Mint 7 Kde. Installed in USB drive. It booted well and worked flawlessly. Later installed the same from USB on /dev/sda7 along with ubuntu 9.04 (/dev/sda9) and Win (/dev/sda8). Up on reboot i could see only "Linux Mint 7 Gloria KDE, memtest86+" for Linux Mint entry on the boot screen. Rest of the OS booted well from there. Here is the menu.lst file content...

Code: Select all

## ## End Default Options ##

title		Linux Mint 7 Gloria KDE, memtest86+
root		(hd0,6)
kernel		/boot/memtest86+.bin
quiet

### END DEBIAN AUTOMAGIC KERNELS LIST

initrd		/boot/initrd.img-2.6.28-11-generic

kernel		/boot/memtest86+.bin  
savedefault
boot

Then i modified the Linux Mint entry like below (took the idea from ubuntu entry)...

Code: Select all

title		Linux Mint 7
root		(hd0,6)
kernel		/boot/vmlinuz-2.6.28-11-generic root=UUID=782b725c-adf6-4bbb-9c14-2b19ed888f50 ro quiet splash 
initrd		/boot/initrd.img-2.6.28-11-generic
savedefault
boot

While rebooting it gave me following error...

Code: Select all

Error : 15

File not found

So I searched for the files vmlinuz and intrd.img and found no vmlinuz file in /boot/. Copied one from USB stick and pasted at /boot/.
Finally rebooted with all the modification. It booted well and I could see the Linux Mint boot screen but landed in Ubuntu 9.04. Previously I installed Kubuntu 9.04 on this same drive and I had no issues with it. Boot loader is installed in /dev/sda.

Again reinstalled Linux Mint on the same drive but I had no luck.

Any help would be appreciated.

It is not surprising that you ended up in Ubuntu because the UUID that you used for the root in the Mint entry is the same as the UUID for the Ubuntu partition.

Change the entry root=UUID=blah blah blah to root=/dev/sda7 and see if that works.

UUID's are a comlete pain in the rear. When you have finished booting have a look around at how to boot with a LABEL (root=LABEL=mint7 would do nicely, assuming you have named the volume mint7 first) Then you would be able to read it easily unlike a UUID.

viking777,

Thanks for the reply.

Yes. you are right. The problem is with the UUID. I changed the entry "root=UUID=782b725c-adf6-4bbb-9c14-2b19ed888f50" with "root=/dev/sda7".Now it is working nicely. There is another method to solve this problem. I took the UUID value for the /dev/sda7 from /etc/fstab then replaced the ubuntu (/dev/sda9) UUID value with mint (/dev/sda7) UUID value. Now the booting problem is over.

But i dont understand why the file,vmlinuz,was not installed
