Upgrading to Windows 8 - How do I reinstall GRUB without reinstalling Linux?

[kentgbailey]

I am upgrading to Windows 8. Will I have a problem with reinstalling GRUB?

[T6]

i haven't played yet with windows 8 but usually you just install it in the same partition you have, leave the linux partitions untouched and when everything is ready in windows you boot the livecd

once loaded you use redombr on the livecd to restore the old boot of linux

i ignore if windows 8 has anything special that could give you problems when adding it to the old mbr but if you already had it working then it should be working again too

Thank you very much, T6.

Do you happen to know,offhand, where I can get documentation for that command and others like it?

Have a good day.

redombr is a GUI tool. It needs root password.
It is available in the PC Menu.

A member of this forum gave my this instructions which has always worked for me, like T6 I haven't tried Win 8 and I hope won't have to do it in a long time, in fact I hope to skip Win 8  

Open a terminal and type in
su - root password - grub

You get a grub prompt and then enter the following

find   /boot/grub/menu.lst

take note of the report you get.
Hopefully you will be able to determine from that which of the returned locations is the PCLOS one.

Then type the following

root   (hdx,y)    #  where the (hdx,y) is the PCLOS partition reported from the last command

setup  (hdx)      #  again where (hdx) is the boot drive


You should get back a report which ends with "Success"

Quit the Console.

Reboot and extract the live CD and hopefully you will boot into PCLOS..

Well, thanks for all the help, but guess what? I just installed Windows 8 and it left GRUB alone. Just thought you would like to know.

Again, thanks for your time and trouble.
