Fedora Core 2 dual boot

Ali je kdo že reševal probleme z dual bootom oziroma grubom povezane s karnelom 2.6 (Mandrake 10, Suse 9.1 in Fedora Core 2) in bi bil tako prijazen da bi rašitev razložil uporabniku Windowsov

Problem je sledeč:
The bug you speak about in the article stems [from] a few subtle,yet key feature changes that have happened within the 2.6 kernel. For 2.6 the kernel developers pulled out certain functionality from within the kernel related to Hard Disk geometry. In 2.6 the developers though that it may be wiser to have user space take control of things such as HD geometry. There is still discussion as to whether or not this was such a bright idea.

In addition to that, it is noted in the bugzilla report that the cause of this bug seems to be a CHS geometry problem. This problem most likely stems from an error within the parted utility, addressing bios incorrectly. In fact, many users with this bug reported that it disappeared after updating their bios to newer versions. Other than that, exhaustive testing has been done on this bug and newer machines did not seem to have this problem. It was almost totally non-reproducible. link

In rešitev naj bi bila:
Here is a much easier way to fix the partition problem, as suggested
by Alexandre Oliva on fedora-test-list:

sfdisk -d /dev/hda | sfdisk --no-reread -H240 /dev/hda

The 240 value worked for me, in other cases probably 255 is better.
Plus, if this helps finding the bug, the kernel still reports wrong
disk geometry in /proc/ide/hda/geometry, even after fixing the
partition table with the correct values. link

Sedaj me pa zanima kako si to rešitev razložiti.

EDIT:
Moj pogled na problem je sledeč: grub ne funkcionira in omogoča le zagon linuxa, medtem ko v primeru zagona windowsov sledi grub error. Situacija je brezizhodna, saj ne pomaga ne novo nameščanje oken ne formatiranje 40g diska na drugem računalniku - nič. Sam sistem je sestavljen iz 6giga diska s Fedoro in 40giga diskom z okni.

Ja no v bistvu je to problem soseda, ki pa mu v linuxih ne dela internet (dial up ISA us robotics sportster) in zato sprašujem jaz - kot grešnik, ki sem mu posnel Fedoro

Kako urediti dual boot oziroma oživiti windovse. Rešitev, ki ni uradna, em sicer napisal vendar mi ni jasno kaj storiti oz kaj pomeni.

PS: Če bi prebral temo in kliknil na linke bi opazil, da je to rasna težava, ki se pojavlja s kernelom 2.6!

Kolikor sem jaz uspel razbrati se težave pojavijo, če ob nameščanju ustvarjaš particije. V primeru, da imaš že ustvarjene pa ni problemov.

Je pa to napaka kernela tako, da jo imajo vse testne različice in ne glede na pritožbe tudi končna verzija.

Mene zanima kaj pomeni:
sfdisk -d /dev/hda | sfdisk --no-reread -H255 -C14593 /dev/hda

Kaj naj bi jaz tukaj naredil? (Zgleda, da se bom med počitnicami moral lotiti branja)

Največji problem je, da je 40g disk povsem neuporaben, saj ga ni možno formatirati oz. se znebiti boot sektorja. Kako to usposobiti?

Ne pomaga niti win XP Recovery Console
bootcfg/rebuild

Lp,

Davor.

ooops. tam pri cat sem izpustil fajl. tako mora bi:

cat tmp.txt > sfdisk --no-reread -H255 -C14593 /dev/hda

Pa -C14593 tudi nisem uporabil. Probaj brez če ne bo delalo.
