Grub behaving strangely
Hi Guys,
I seem to have misunderstood something about how Grub works...hers what my problem is... HD1: 2 Windows partitions HD2: 1 WinXP and 1 FC5 installation both in extended partitions Now the problem is if I install Grub on the MBR it works fine but gives me error 22 when I try and boot into XP or Win2K... Now ppl at home need Windows so I pop in the Win Cd and get into recovery console and do a "fixmbr" and Windows comes up ..problem is Grub is gone...this makes sense though coz Windows overwrites the MBR each time....why?...I dont know... ============================ I now go into Linux Rescue...go into... grub>find /boot/grub/stage1 (hd1,7) grub> root (hd1,7) ext2fs..... grub> setup(hd1) ...........Grub installs but Windows is gone.... ======================= So now I read up a bit and find out that if Windows is on a non-first hard disk Grub wont boot it and I have to use "map" to trick it... so now I go into /etc/grub.conf Title WinXP rootnoverify(hd1,7) #Thats my partition on which WinXp is map (hd0) (hd1) map (hd1) (hd0) chainloader +1 makeactive ============== I've removed the device.map and recreated it...no issues there either... =============== I reboot...no luck...Linux boots like a charm...Evil Bill does not...Im sicking of popping CD's in and out....can any1 help me out here...??? Why does Grub not recognize Windows partitions...I mean..its always worked so beautifully for the last 4-5 years....and detects anything... I've wasted a whole Saturday trying to get this thing fixed... :( All help is appreciated.... Cheers Arvind p.s....Let me know if you want grub.conf or my fdisk -l output .. I'll paste it here... |

title Windows XP rootnoverify (hd0,0) chainloader +1 You don't have to worry about the other partitions as they will load through Windows, they are not Windows partitions (unless for some odd reason you have installed differently on all 3 of them), they are NTFS partitions. |
Thnx 4 the response...think you misunderstood me a bit...I fixed the thing BTW .. chainloaded the Windows on my first disk and then boot.ini did take over...
The problem is .. why doesnt grub directly bootable Windows partitions on my second hard disk...Here take a look..maybe this will make it clearer... ================================ root@attack lib]# /sbin/fdisk -l Disk /dev/hda: 10.2 GB, 10205282304 bytes 255 heads, 63 sectors/track, 1240 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 319 2562336 7 HPFS/NTFS /dev/hda2 320 665 2779245 b W95 FAT32 Disk /dev/hdb: 40.0 GB, 40060403712 bytes 255 heads, 63 sectors/track, 4870 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdb1 1 127 1020096 82 Linux swap / Solaris /dev/hdb2 128 4869 38090115 f W95 Ext'd (LBA) /dev/hdb5 128 764 5116671 7 HPFS/NTFS /dev/hdb6 765 2039 10241406 c W95 FAT32 (LBA) /dev/hdb7 2040 2778 5935986 7 HPFS/NTFS /dev/hdb8 * 2779 3670 7164958+ 83 Linux [root@attack lib]# ================================= I want to directly boot /dev/hdb7 after installing Grub which isnt happening... Grub loads up...and if I boot into Windows ...it takes me to teh WIndows boot loader...where I can select...I need something like 1.Fedora core 5 2.WinXP 3.Win2K Hope this helps... Cheers Arvind |
