Hi everybody,
I guess that I've a pretty typical question as regards a pretty typical problem.
On my laptop I'm currently double booting Ubuntu 8.10 with windows XP, OK straight forward.
Now I want to trial the Windows 7 beta, So now I want to tri - boot.
I understand that when I install win 7 I'll lose GRUB, but that it's possible to reinstall GRUB and set both win xp and win 7 as options within the start up menu.
The following guide sort of makes this sound pretty simple...
.....Then, you either need to adjust the W7 boot loader with EasyBCD (instructions can be found on the apcmag guides) or, preferably, reinstall the GRUB Boot loader by doing the following:
Insert the Ubuntu Live CD (or flash disk or whatever) and select "Try without changes to computer." Once it loads up, open a terminal and type "sudo grub"
Then enter the following commands in order.
Code:
- root (hd0,0)
- setup (hd0)
- quit
- exit
Reboot, and it will go directly back to Ubuntu. Now you'll need to edit GRUB to get the Windows partitions. You have two options - enter BOTH Windows partitions into GRUB, or just enter W7, and use the W7 bootloader to then select XP. To edit grub, key into the terminal "sudo gedit /boot/grub/menu.lst" (or replace gedit with whatever program you prefer) and make sure that the option "hiddenmenu" has a '#' in front of it to make it visible. Then go to the very bottom where all the Ubuntu kernels are listed and add the following (NOTE: The location (hdX,X) may be different for your install):
Code:
title Windows XP
root (hd0,1)
makeactive
chainloader +1
title Windows 7
root (hd0,2)
makeactive
chainloader +1
My problem is with not understanding what to do with UUIDS.
Im happy with hd0,0 etc but what do I do with uuid 22cd1ee4-c7b3-4259-97ce-7d1dc60ed939 ??
For example I need to enter the following..
Code:
- root (hd0,0)
- setup (hd0)
- quit
- exit
But if on my system windows xp is sitting nicely at (HD0,0)
and presumably Ubuntu starts on (HD0,1) and so on
(see code)
Code:
s -l /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 2009-02-07 22:24 19c3fba1-5c7b-4780-badb-d820bb8543a4 -> ../../sda5
lrwxrwxrwx 1 root root 10 2009-02-07 22:24 22cd1ee4-c7b3-4259-97ce-7d1dc60ed939 -> ../../sda2
lrwxrwxrwx 1 root root 10 2009-02-07 22:24 74F809DBF8099C8C -> ../../sda1
lrwxrwxrwx 1 root root 10 2009-02-07 22:24 defa2a5f-afb1-487e-9d13-842ca482acf8 -> ../../sda6
How do I proceed further???
Any help will be very greatly appreciated.
