Win95+NT3.51+Linux Installation problem
Posted on 1997-05-12
I'm using a P133 with a 1.6 Gbytes HD, IDE Cd-Rom and 32 Mbytes RAM. I have my HD partitioned as follows:
1 DOS primary partition of 300 Mbytes (DOS+Win3.1)
1 extended partition which includes:
1 NTFS partition of 500 Mbytes (NT 3.51) C: under 95
1 ext2 partition of 468 Mybtes (Linux RedHat 4.0)
1 swap partition of 32 Mbytes (swap memory for Linux)
1 FAT partition of 300 Mbytes (empty) D: under 95
Recently, I decided to try Win 95, so I installed it on the DOS primary partition. After doing it, I'm unable to acces to NT nor Linux. If I try to enter NT, the system crashes. I've tried to repair it, but the repair disk gives an error, and if I try it without the reparation disk, the NT installation program complains that it can't find any NT installation in the HD. This is strange, as when installing Win 95 it complains that there is a NTFS partition and it's being unable to read the files in it.
If I try to enter Linux, it detects correctly the HD, but then I obtain a bunch of errors when trying to access to the root partition.
I tried to recover the MBR, as I supose Win 95 overwrites the existing partition table, but if I try to do it from the NT installation program it recognizes the partitions but they appear as unformatted or damaged. Also it says that my HD has more than 1024 cylinders, when in fact, it has 811 in LBA mode (3243 in NORMAL mode), and it gave this message never before I installed 95. Even the Linux fdisk, says that there is a HD error and can't run.
I' ve tried the following, I've reformatted the primary partition and installed DOS again, but fdisk gives a disk error when I try to run it in LBA mode. If I put it in NORMAL mode it sees the primary and extended partition, but the size of the HD is too small (I think quite logically, as it only can manage 1024 cylinders). So, I reinstalled 95 again but, still, it continuosly crashes, or shutdown or gives me an error in a VXD, even if I uninstal almost every controller, plug and play and other stuff. Even with this minimal configuration it hangs or reboot or crashes. However, 95 detects the D: unit (the other FAT formated partition), although it says that it has some problems (due to fact that I have some files from NT with long names), and once I saw a message about a failure writing to the D: unit.
Well, sorry for the long message, but I wanted to describe the problem as detailed as possible. I only want to recover the data in the Linux and NT partitions. Any ideas?
Thanks in advance:
