RE: [expert] kernel panic, can not mount root fs
One bizarre option you might try - if you just want to recover data and it is vital - try finding an Amiga, plug your hd in to it and run... oh drat my mind is a blank, there is a file system on aminet that allows you to mount unix/linux partitions and read from them. Last time I used this 8 months ago there was another version that reads AND writes. Does anyone know what the file system is that I'm thinking of? I'll check my old notes and see if I still have the name somewhere. Just a suggestion...

Re: [expert] kernel panic, can not mount root fs
(I'm not saying that you necessarily have to re-install, but I have no further suggestions as to how to recover your linux data) There's no need to add any extra partitions between Windows and Linux partitions. You just need to make sure that when you do your install, that you install Windows first. It is not necessary to partition your drive first, but you can. I've done it both ways: partitioning before, and after windows install, and both were successful. After you do the install, make sure you've defragged the disk in windows, and then you can partition during your linux install. I strongly recommend, after you install linux, that you reboot back into windows to make sure that it has properly recognised the space you allocated to it in its partition. That's the only problem with Windows, is that it may not recognise the partitions. It took over a year before windows would recognise the new partitions when it happened to me. go figure. > well i agree windows has screwed up your partitions, > you may be able to use partition commander to repair the damage, but as for salvaging your data, most likely only windows data can be salvaged, im unsure how to salvage data from linux partitions, the cause seems to be that when windows was writing to a partition it misread the data table and over extended the partition it was writing to ontop of another partition which happens to be your /root partition. > maybe you should add a small extended partition between your linux and windows partitions. that way you may have a small buffer of protection against windows write errors like the one you encountered, another thought is using vmware, however if you intend to log online with windows using a virtual machine such as vmware would be a bad idea. > > have fun! > [EMAIL PROTECTED] wrote: > > > > Sounds to me like Windows didnt recognise your partitions properly, and > > installed over the root partition of Linux. > > > > I've had this happen to me before.

Re: [expert] kernel panic, can not mount root fs
Of course # of primary partitions is not os-dependent.

What are you talking about. Windows has nothing to do with the # of primary partitions which can be used. Any drive can contain up to 4 primary partitions. The 1 limitation is for logical (extended) partitions and this also is not dependent upon the OS being used. Charles (-: Forever never goes beyond tomorrow.
Re: [expert] kernel panic, can not mount root fs
well i agree windows has screwed up your partitions, you may be able to use partition commander to repair the damage, but as for salvaging your data, most likely only windows data can be salvaged, im unsure how to salvage data from linux partitions, the cause seems to be that when windows was writing to a partition it misread the data table and over extended the partition it was writing to ontop of another partition which happens to be your /root partition. maybe you should add a small extended partition between your linux and windows partitions. that way you may have a small buffer of protection against windows write errors like the one you encountered, another thought is using vmware, however if you intend to log online with windows using a virtual machine such as vmware would be a bad idea. have fun!

The problem could also be that you have more than one primary partition. Windows only supports one (visible) primary partition, all the rest needs to be extended partitions, if not they're toast.
Re: [expert] kernel panic, can not mount root fs
Sounds to me like Windows didnt recognise your partitions properly, and installed over the root partition of Linux. I've had this happen to me before. The only solution that I found was to re-install the whole lot, both OS's, making sure that windows recognised the partitions that were allocated to it. "Ingo P.
