Hey guys.
I recently installed ubuntu, for various reasons, but I am a gamer and sometimes playing a game is more alluring then other activities.
The thing is I have windows 7 installed but i am unsuccessful in configuring GRUB to dual boot.
My harddrives are:
1000 GB storage ( /dev/sdc1)
290 GB ubuntu 9.10-amd,64 (/dev/sda1)
2 GB swap (/dev/sda2)
104 GB Windows 7 (/dev/sdb1)
350 GB unallocated.
Dump from fdisk -l
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xdf73df73

/dev/sda1 * 1 38661 310544451 83 Linux

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders

/dev/sdc1 1 121602 976759808 7 HPFS/NTFS
Now adding an entry to GRUB.
This is my 40_CUSTOM, located in etc/grub.d/.
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry "Windows 7" {
set root=(hd1,1)
chainloader (hd1,1)+1
}
Now when i run:
sudo update grub
It seems to work but i get one line of output I am bit worried about.
ls: cannot access /media/-: No such file or directory
Anyway I restart my computer and try to boot windows 7.
With chainloader +1 the result is.
bootmgr is missing.
With chainloader(hd1,1)+1 I get an error message about an invalid name..
Seems to me that i have pointed to the wrong disc, but sdb1 = hd(1,1) right ?
**UPDATE**
Solved the current problem, but when running
sudo update-grub
It doesn't locate my windows boot files located in /media/Windows/windows/boot.
Anyone have an idea ?
