Arrggggggghhhhh!
Thanks to everyone for their suggestions of help.
I had erased my Linux Partition to make space for Windows files,
forgetting that the Linux controlled the LiLo boot and so now I can't
get into Windows.
I'm afraid this is nonsensical. LILO is normally installed in the master
boot record of your hard disk - the one set in the BIOS as the bootable
device. There are other scenarios for installing a GNU/Linux bootloader,
but I don't see any possibility of the removal of GNU/Linux disabling
Windows from booting up.
Windows - I presume you are talking of an NT-derived version such as Windows
XP - uses a bootloader that lives in the active primary partition on the
bootable hard disk. Even if you were to remove your GNU/Linux partitions,
LILO would still be in the master boot record and its Windows entry would
still be pointing to the Windows bootloader.
My guess is that you've been playing around with something like Partition
Magic and that you've screwed up your partition table, leaving your Windows
boot partition unbootable.
I have tried to reset the Administrator password in order to get my
Windows machine into Recovery mode.
I don't do Windows, but from what I've read about it, resetting the
Administrator password would require you to boot into Windows first. You
claim that this is not possible, so how could you ever get there and what
do you hope to accomplish by resetting a password?
This is still not working! Maybe I am changing the wrong password?
If there is one Administrator account on your system, it will have one
password only.
There are 4 or so partitions on this hard drive. I think I know which
one used to be the Linux partition.
You /think/ you know? As a system administrator - and especially to your
own machine - it is your business to know. ;-)
Is there a lightweight (eg. I don't have a CD-burner, just a floppy
drive) way to install a new OS on the old Linux partition?
Maybe you can get your hands on an old copy of OS/2, although for good
measure I have to add that this may not be legal. I don't do proprietary
software, but it may be so that a purchased license may not be transfered
to another person.
Note that you can also install another copy of Windows on an empty
partition, as long as there is an active primary partition to write the
Windows bootloader to. If there is already a Windows bootloader installed,
the new install will add its entries to the original bootloader.
Would this help me to recover my old files?
What old files are you talking about? Your GNU/Linux files? If you've
erased those partitions or if you've deleted those files, then you'd have
to get into some serious hard disk forensics to retrieve them, I'm afraid.
And then it all also depends on which filesystem you were using.
All I really want is to set up LiLo on the machine again and get back into
Windows.
Use your official Windows XP CD/DVD to boot from and use the repair console
or whatever it is called. There should be two utilities on that CD
called /FIXMBR.EXE/ and /FIXBOOT.EXE./ The first one will erase LILO from
the MBR by overwriting it with an MBR that's compatible with MS-DOS, OS/2
and Windows. The second will - most likely; like I said, I don't do
Windows - set your Windows partition as active/bootable again.
I have spent all day trying to crack this.
Thanks for all your help.
