I have a really weird problem.
I installed Linspire on my dad's computer last weekend, and everything worked fine. Already had Windows 2000 on it, so we made an extra partition with partition magic (a FAT32), installed Linspire on that partition and everything was ok.
Now, a day later, my dad reboots his computer after installing an update of Zone Alarm (from Zonelabs it's a firewall) and all of a sudden he gets a blue screen saying: inaccessible boot device.

Now you may wonder why I'm asking this question here. But to make sure the problem isn't Linspire I'd like to know what the file is that configures the dual boot (when you chose for Linspire or Windows). I just want to make sure the boot screen (I don't know the name) isn't wrongly configured in some sort of way. I don't really think that's the problem, actually, because it already starts to boot windows, but you never know...
On my computer, I have Mandrake and I know there the file is named lilo.conf, because I had some problems with that after inserting (?) a second hard disk in my computer.
But I can't find how the file is named in Linspire. Or even if there is such a file.
So... Well, I'm really worried it's a bootvirus. But I just want to make sure it's not because we installed Linspire wrong or something like that.

Who can tell me where I can find the file that configures the dual boot???
Or if anyone knows a solution except that it's a virus. Or has experienced the same problem with Zone Alarm. Please tell me.

Thanks in advance!

You made a long post but some important things is missing. So I gived a short answer here for your main questions. You should answer my questions to receive more details answer.
You have know where is the file lilo.conf but you don't know what it is in Linspire, so I suppose that your linspire is using grub boot manager. Its config file is stored in /boot/grub/.
The file name may be grub.conf or menu.lst. It depends on your system. If you don't see these file, check all the file in your /grub directory (there is not so many files).

If the info above don't help, please answer these all questions:
- Is your disk broken?
- Can you boot into any OS on that computer?
- How was your hard disk partitioned?
- Either virus on windows or Zone Alarm doesn't affect Linspire so, check you have infect an boot virus which has destroy your master boot record.
- How was your PC before you face that problem

Thanks for replying so quickly!

I couldn't find a grub folder or a boot folder. But maybe I didn't look hard enough, so I'll give it a go again in a few minutes.

- Is your disk broken?
If you mean like 'broken' like in two (sort of). No it's not.
- Can you boot into any OS on that computer?
Yes, I can boot in Linspire (there's Windows 2000 and Linspire on that computer).
- How was your hard disk partitioned?
Well, there's only one hard disk.
In windows it's:
A: floppy
C: Windows NTFS
D: FAT32, My documents, no OS
E: CD
F: Linspire FAT32
It's a bit weird, the sequense, but that's the way it is.
I don't know how it is in Linspire, because it appears that some partitions are missing. Sort of...
hda : empty
hda1: windows
hda5: My documents, no OS
hd6: Linspire
So, it seems like some partitions are missing... On my computer, I think, there are not any missing. I never noticed a strange sequence.
- Either virus on windows or Zone Alarm doesn't affect Linspire so, check you have infect an boot virus which has destroy your master boot record.
I couldn't find anywhere how to do that, so maybe if you could explain how? I really would like to find that out indeed.
- How was your PC before you face that problem
The PC was working great. Well, no, it was not...
The feed (?) of the computer had sort of blown up. So we had it repared by a specialist. But after that it was working perfectly fine. I'm not sure whether the hard disk could have been damaged after all. The mechanics (?) said it wasn't, so... And besides, Linspire is working fine.

Thanks again for helping!

So, we are gradtually figure out your problem.
You mean you can still see the boot manager screen and can boot into Linspire but when you choose windows it said "inaccessible boot devices", right?

Then, I need two more information.
- Can you access the windows partition?. Your disk is not broken but this partition can be broken and could not be access.
If all the partition on your disk then:

- You said you don't have a /boot folder in Linspire??
So strange to me, I think any linux system must have a folder like this, this folder contains the core boot file of linux (just like the file command.com in windows), so please check again and give me the definite answer, you have the /boot folder or not???.
Assume that you have a /boot folder. Then you will have to reconfigure the boot loader to boot into windows.
There is three possible case.
1) You are using another boot loader, not the for linux one.I can't help you then.
2) you are using lilo, like your mandrake PC. Because you have experienced with lilo but I don't so sorry that I can only give you that remind: Then lilo config file can be anything depend on your distro, lilo.conf is a popular name but not the only name..
so dive into the folder which contains the lilo and seek for a text file which look like the config file.
3) You are using grub.
Then dive into folder /boot/grub (you must have that folder if you are using grub).
Seek for the file grub.conf or menu.lst. If you cannot find these file, read any text file in the folder which contains these words: "kernel" and "initrd"
The add the following line to this file (note that only root can edit files in /boot folder):
then reboot the computer. When you see the screen which ask you to choose a operating system, choose the line "windows 2000 test"
You can still use the following command to boot into windows. Just press c at the OS chooser screen and type:
If this post don't solve your problem, give me more info, what did you see when your computer boot, what was displayed when you try to boot into windows and so on

Thank you very much for your time!
But my father reinstalled windows and now it's working again.
He didn't have enough patience to let me figure out the problem. I can understand that, but I'm sorry he did, because I found it quite fun to try to figure out the problem. And it would be a lot handier if we could fix the problem without having to reinstall windows.
I think after all it was a partition problem. When creating the partition for Linspire, Partition Magic couldn't format it. But when we tried to format it ourselves it did.
So that was kind of weird. Though, on the other hand, we didn't touch the C partition with windows on it, so it's still really weird...

Next time, I'll install Mandrake, because it makes a partition itself so we don't have to do that. And I'm familiar with Mandrake, so we wouldn't have so much trouble finding a solution.

Thanks again very much for your time, if I need help again (hope not), I know where to go!
