what's wrong with my HDD

ccmilan · 05-25-2005, 06:27 AM

I installed winXP and debian on my computer,
when i type
fdisk -l, it warns£ºcan't open /dev/hda
cfdisk, it warns£ºFATAL ERROR: Cannot open disk drive
what's the crux?
Also ,i tried to create a linux link file linux.lnx by:
dd if=/dev/hda8 of=/mnt/hda1/linux.lnx bs=512 count=1(I have a swap partition and / partition hda8),and added a line in boot.ini c:\linux.lnx="Linux"
I thought this way i can utilize the windows OS Loader to boot my linux system.
But this wouldn't work, i got a blank screen.
Is the above two problem related?
Thanks.

Dunno, but I'd guess something is wrong with the partition table. Give some more information, please, will you

That would work when you installed GRUB / LILO in /dev/hda8. Usually it is in /boot when it is not in the MBR. Infos please... (Btw, just for the record, this is not a link in the Linux-sense, it is a file of 512 kb size </nitpicking>)

Possibly but I doubt it. Give some more information also on how you started the system (or did you?) and how you made dd work...

Thanks for your comments.
I installed winxp,then linux(two partitions,swap and /),and grub in mbr instead of hda8.
There seemed to be something wrong with the debian installer's partition tool,It failed a few times,complaining "can't create partition XXX",finally it succeeded,I don't know why.
The system looks fine except the two problems I mentioned.
It boots successfully via grub,but can't boot via windows OS Loader.

I suggest you have a look at this with som other tool like e.g. (gnu)parted (comes with debian?) or else try

ftp://bmrc.berkeley.edu/pub/linux/re...ble-0.3.tar.gz
http://www.stud.uni-hannover.de/user/76201/gpart/

Of course not

. The GRUB-loader stage resides in the MBR of /dev/hda. Do a

Code:

dd if=/dev/hda of=/mnt/hda1/linux.lnx bs=512 count=1 {NOT /dev/hda8}

and copy / move linux.lnx to C:/.

After that your system starts with GRUB, you should be able to select WinXP, get the XP-loader and have an option there to jump back to GRUB

. At least that's the way I do it with NT...
