Booting XP Grub Error 15 problem

Postby Merlin7777 » Fri Apr 04, 2008 0:02

Hey all!!!

I don't know what changed, but I just tried to boot my XP install today and I received a shock! It didn't work?!

Okay, so why it surprised me is that I have been able to do it for several weeks now and it worked fine. I haven't touched Grub, nor installed a new operating system.


Again, I don't have a clue as to what could have caused this issue. I had an original list from my Ubuntu install that I had copied over to the grub.conf file in order for my other partitions to be recognized. Before I had installed Sabayon, when I was just using the Ubuntu install, everything worked fine. I could boot XP or Ubuntu when ever I wanted with the provided Grub settings.

Then I installed Sabayon a few weeks back, appended the old Ubuntu settings to the grub.conf, and everything was dandy. Worked great.

But now I get:
root (hd0,0)
Filesystem type unknown, partition type 0x7
savedefault

Error 15: No file found.
Press any key to continue....

So I did some research and replaced "root (hd0,0)" with "rootnoverify (hd0,0)".
That got rid of the "Filesystem type unknown..." error.

But I am still receiving the Error 15 for some reason.

sudo fdisk -l gives me this:

Oh, and I can mount the partition just fine in Sabayon. I can look at my Program Files folder perfectly and whatever else you can think of.

So, what do you guys think?

remove the stuff about Ubuntu (unless it's still installed), and for the windows partition make the
Code: Select all
rootnoverify    (hd0,0)
savedefault
makeactive
chainloader     (hd0,0) +1
into
Code: Select all
rootnoverify    (hd0,0)
chainloader +1


hopefully that'll work for you - otherwise something may have gone wrong with windows.

That fixed it! Thank you so very much!! I find it interesting though how it worked fine with those settings until recently. Oh, well, they are of no consequence.

Thanks again, your a life saver.
