To help you, I will first explain the process of booting OS-es: After the computer has done POST, it checks to see if there is a MBR (master boot record) on ide0, hard drive 0 - this is your master hard drive on your first ide. It loads the MBR and the MBR (usually) loads the boot record of the partition which is set active. The boot sector then boots the operating system. Linux uses LILO (linux loader) to boot itself up. Lilo is the first thing your computer will load, because LILO (usually) will load from the MBR (you can make it load from your installed partition, but I do not recommend it). The OS Loader that comes with NT based OSes sits in the boot record of the installed partition. It ALWAYS loads after the MBR. Windows NT installs usually do not mess around with the MBR, this is why you could load Linux after the installation of NT (NT installation didn't remove LILO from MBR). However, 95/98/Me installs DO mess with the MBR, they clean up the MBR and set it to load the boot record from the partition where you installed 95/98/Me. - You practically lost your LILO, but your Linux is still there, intact! To solve the problem, you need to get into your Linux somehow, and from there to run: #lilo This will reinstall LILO on your MBR. There are different ways of getting into Linux. With RH you have a handly little tool called loadlin located in the dosutils directory of the CD. Reply (if you still have the problem, and tell me your distro, whether you have loadlin, etc.) Nick -- --------------------- Nikolai Hristov Slayter Box 1194 Denison University Granville OH 43023
