Hello everyone,

I previously had a Windows Vista / Fedora dual boot on my desktop computer which worked with no problems. I have today replaced the Fedora O/S with CentOS 5 64bit and now I can not boot into Vista. When trying I see the following white text on the black screen:

Booting 'Vista'

rootnoverify (hd1,0)
chainloader +1

But nothing happens after this. CentOS boots fine, Here is the grub configuration:

Grub.conf
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-128.el5)
root (hd0,1)
kernel /vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup01/LogVol00 noapic rhgb

quiet
initrd /initrd-2.6.18.128.el5.img
title Vista
rootnoverify (hd1,0)
chainloader +1

Is some one able to assist?

Many Thanks
Patrick

title Vista
rootnoverify (hd1,0)
makeactive
chainloader +1

Hope that helps.

Your vista entry (rootnoverify (hd1,0) shows that it is on a second drive, separate from Fedora. Is that the case? If so you would need to change the entry if vista is on a second drive to:

title Vista
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

If they are both on the same drive, you need to change the entry. Not knowing how many partitions you have it's hard to guess. Post the output of the 'fdisk -l' command run as root (lower case Letter L in command).

Hern,

Thanks for the quick response - I added the makeactive line into grub.conf but it unfortunately has not resolved the problem - any further ideas?

Yancek,

Thanks for getting abck to me, I did wonder about the HD mappings but being a newbie I didn't know how they should read. I have 2 HDD's but the primary SATA drive has both O/S's installed. It has 3 partitions:
1: VISTA NTFS
2: CENTOS EXT2FS
3: NTFS, a backup partition I have

Here is the FDISK -l output:
Device Boot Start End Blocks Id System
/dev/sda1 * 1 38245 307200000 7 HPFS/NTFS
/dev/sda2 38246 38258 104422+ 83 Linux
/dev/sda3 53543 60802 58304512 7 HPFS/NTFS
/dev/sda4 38259 53542 122768730 5 Extended
/dev/sda5 38259 53542 122768698+ 8e Linux LVM

There is an IDE drive with an old version of XP and Fedore installed, I wonder if that is confusing grub a little.

Thanks
Patrick

Shouldn't vista be on hd(0,0) then if its on the first partition of the first hard drive?

Hern,

Changing rootnoverify (hd1,0) to rootnoverify (hd0,0) has solved the issue.

Your help was much appreciated.

Patrick

Anytime.
