Win XP and Fedora Core 5 conflict


Has anyone else run into this problem. I swear that WinXp can see and try to use; but fails, fedora core 5. I'm still trying to learn linux.

MB: Gigabyte GA-8IPE1000 Pro rev 1, Biosver FG i865 intel chipset
Processor: dual core intel Pentium 4 CPU 2.60 GHz

Windows XP Side of Box
HDD C: Maxtor 6B160P0 - drv.size 160 GB, used by winXP 60 GB
HDD D: Maxtor 6y060L0 - drv.size 60 GB, used by winXP 30 GB
HDD H: Seagate ST360020A 60 GB 0 GB, used by winXP 0.0 GB

Fedora Core 5 Side of Box setup in LVM ext3fs
HDD A2 Maxtor 6B160P0 used by fedora - 96 GB
HDD A3 Maxtor 6B160P0 used by fedora - 102 MB
HDD B2 Maxtor 6y060L0 used by fedora - 30 GB
HDD C1 Seagate ST360020A used by fedora - 60 GB

The seagate drive is hooked in via a Promise 66/100 scsi card

On a dual boot machine, dual core intel Pentium 4 CPU 2.60 GHz, with both WinXp and fedora core 5, I was cleaning up the windows side of the drives so as to reinstall WinXp on it's side.

While under fedora core 4, WinXp would never reformat the linux side of the machine. With Fedora Core 5, it did. Without warning of the size it was formatting, it reformatted ALL of HDD B2 linux side also.

What is so different about fedora core 5 that an updated standard Windows XP Home Edition can take out the Linux side?

Now, A2, A3, and C1 of Fedora Core 5 are are intact and untouched. I can understand why grub will not boot with kernel panic going on. FC5 Rescue insists that there are no linux files at all. So that's out.

Is there any program that can run on windows and yet see and copy some of the linux files that are still there.

How can this happen and how could it have been prevented. Window printed to screen that it was formatting 30 gig, approx. and then proceeded to do the entire drive, including the linux side. HOW?

If anyone can come up with any ideas or help I would sure appreciate it. I'm on a very fixed income and can not come up with much money to go to a drive recovery business. But somehow, I must at least try to get at least 2 certain files off before reinstalling fedora. The files are new and were going to be backed up and then this happens. Is there a linux to use that can be run from cd so as to recover my files, maybe?

Thank you in advanced for any assistance you can give me.

Normally if you partition a hard disk you can tell XP and FC5 to install themselves inside. Your problem only arises by letting an OS a free hand to change your hard disks. Using LVM doesn't help either because it will bridge several disk together to form one unit.

You can get a LiveCD, almost anyone will do, and use its fdisk program to delete the unwanted partitions and re-created the original partitions. On a reboot those previous partitions should be back with you unless you have overwritten them. This method only works if you have a record about the sizes and partition types.

If you create a type 7 NTFS partition, say 25Gb, you can tell XP installer to install XP inside it.

For FC5 and starting with no other LInux you need two partitions; a Swap about 1Gb and 5Gb for FC5 itself in partition type 82 and 83 respectively. Tell FC5 installer you want mannualy selecting the partition, edit the 5Gb partition for mouting "/" or its root and formatting it in Ext3 then everything will come out as you instructed.

There is no conflict between XP and FC5 but every OS installer wants to outmanorurves other systems by grabbing all the disk areas and you let XP and FC5 get away with murder! Have a look at the second last link in my signature as FC5 and XP were among the 100+ systems reported.

My problem was that winXP JUMPED the partition. So part of my LVM is missing.

My winXP is installed NTFS for the hda1
VFAT is on hdb1, but windows ignored partition and formated the whole drive, 30 gig of which, was Linux partition. And VFAT had the other half of the drive hdb1 (D:\ ) So now the the LVM has changed and I don't know how to fix it to try to recover a couple of the files, IF, they are still there.

My two questions are basically,
1. How do I fix a changed LVM info for the linux side and reinstall enough that MAYBE I can recover the info.

2. How and why would WinXP jump the partition, and format the ENTIRE drive? I noticed that winXP now lists the linux drives under my computer but does not seem to kow what kind of system drives they are.


Thank you for your earlier advice. It helped with another problem. And I will try LIVE CD and see if IT can at least see the remainder of my linux, to try to recover the files.

I don't use LVM and could not offer advice on the first question. However I expect some LiveCDs to be able to read your LVM if it is still intact. THis is based on obeservation of many installers and kernels trying to search for RAIDs and LVMs on booting up.

On the 2nd question I do believe XP will ask your permission to use the partition/drive before installation. Like I said most people don't bother and XP will grab as much as it find.

XP does not support Linux and will regard a Linux partition as "foreign" like a Unix or something ready for conversion. It can detect its presence and can format and delete the partition at the owner's wish. If XP supports Linux it will need the ability to read EXT2, EXt3, Reiserfs file systems etc and probably has to undersatnd BSD and Solaries partitions too. It is a selfish system and for commercial interest will not touch anything that can reveal its own shortcomings, like dealing with bootloaders. On the other hand it cannot afford to be ignorant of the partitions used by other systems.
