Re: Dual OS boot up problem

OK lets try this......

when you try to boot up and you get left at the grub prompt

grub>

type

set root=(hd0,5)

and press enter
then

linux /vmlinuz root=/dev/sda5 ro

and press enter
then

initrd /initrd.img

and press enter
then

boot

and cross your fingers and press enter .............

if this works run

sudo update-grub

as soon as your loged in

if it dose not work run the live system again and open dolphin and navagate to the kubuntu partition and open a terminal thare (you should be seeing bin,boot,cdrom,dev,ect,and,and) then run

ls -l

and post that .

Re: Dual OS boot up problem

Thanks Vinny,

OK lets try this......

when you try to boot up and you get left at the grub prompt

grub>

type

set root=(hd0,5)

Error 27 : Unrecognized command

Grub gives a list of possible commands:

background blocklist boot border cat chainloader clear cmp color configfile debug displayapm displaymem embed find foreground fstest geometry halt help hide impsprobe initrd install ioprobe kernel lock makeactive map md5crypt module modulenounzip pager partnew parttype password pause print quiet read reboot root rootnoverify savedefault serial setkey setup shade splash image terminal terminfo testload testvbe unhide uppermen uuid vbeprobe viewport


Could I use some of these commands instead?

Re: Dual OS boot up problem

Ah, I can boot up linux with the following commands (thanks for your help Vinny)

kernel /vmlinuz root=/dev/sda5 ro
initrd /initrd.img
boot

I ran an update on grub, but I still only get the grub prompt on restart (so still no access to windows).
Could it be I've got grub installed incorrectly? In the wrong place? grub installed twice??

Re: Dual OS boot up problem

I must confess I'm at a loss at the moment..........

I wanted the "ls" to make sure the system links vmlinuz & initrd.img where their and pointing to the right stuff as grub.cfg was concerned

I'll keep thinking and if I can will be back with more.........................or someone else will
