ntldr missing on red hat boot


Hi

I installed red hat 9 some time ago - have 2k on my primary partition and one day when messing around deleted my grub boot loader. Anyway i had a copy of my boot disk so rather than getting bogged down in restoring my bootloader i continued to use the boot disk for my red hat sessions - this was fine until yesterday and i get the message missing ntldr every time i insert this disk to access red hat - i know this might not strictly be a red hat problem but nevertheless if anyone could inform me how to get round this i would be most appreciated. I have looked on the net and most sites say its a problem when installing 2k over 95 or 98 which isnt the case - any suggestions would be welcome

cheers

johno

i think your floppy disk (not floppy disk driver) is crashed.

if u didnt change partition table after installing redhat, do the followings to restore your old bootloader.
boot from redhat CD1 and give

linux rescue

option. it will ask about networking say "no" cos it s not necessary, then it will ask about mounting root partion to /mnt/sysimage, say yes for this question. u will be in a console with root rights. give the following commands:
#chroot /mnt/sysimage
#grub-install /dev/hda

PS: if your HDD isnt primary master driver, change /dev/hda to correct disk option. (/dev/hdb /dev/hdc /dev/hdd). u may look at partition table with "fdisk -l" command.

NTLDR missing when trying to boot WinXP

Hi there!

I have a similar problem as johno but the other way around...

I just installed the FedoraCore 2 on my lap-top with WinXP and tried to make the dual-boot. The result is that i can boot my computer with Fedora but when i try to boot with WinXP the message of "NTLDR missing" appears and i have to restart.

I can give you the partitions as they appeared during the installation of FC2 and hope you can give me a solution (part, type, size, mounting point):

/dev/hda1 VFAT 18607MB
/dev/hda2 EXT3 100MB /boot
/dev/hda3 VFAT 8MB
/dev/hda4 extesa 9901MB
/dev/hda5 SWAP 992MB
/dev/hda6 EXT3 8910MB /

I have tried to manually boot from grub but all i get is the same result. If i type boot (hd0,0) i get the message "Error8: Kernel must be loaded before booting" and if i list all the partitions i get something like this:

Partition number 0: Filesystem type is FAT, partition type 0xc
Partition number 1: Filesystem type is ext2fs, partition type 0x83
Partition number 2: Filesystem type is FAT, partition type 0x1e
Partition number 4: Filesystem type is unknown, partition type 0x82
Partition number 5: Filesystem type is ext2fs, partition type 0x83

Note that partition number 3 is not detected (!) and i guess this was the one to boot with WinXP... and partition 4 is type unknown, so i guess i did something wrong when partitioning with Fedora insaller... (i'm a complete newbie)

I would like to know if there is any possibility to recover the WinXP, any suggestion will be welcomed.

Thanks in advance and greetings from Barcelona,
Nan
