I'm about to add an 80G sata second drive to a Dell 2.8G XP computer that I wish to boot to both Linux and Windows XP. I have the FC5 DVD from which I intend to do the install. What do I need to know before I start? XP Home is already installed and I have no way to reinstall it, no o/s CD's are provided. There will probably be choices for locating boot and grub, what is best to do there? Any suggestions, reference material, etc. appreciated.

Hi Bob Goodwin! Your basic plan sounds quite good. Leaving the XP disk alone and using a new FC5 disk sounds very good. Pointing (useing the XP boot loader defaulted to FC5) from XP as others have suggested, why not? I will be doing a multiboot Ubuntu, FC5, Suse, Knoppix, and probably Solaris in the next month or so. What I would really like to do is to run a Linux (probably Ubuntu right now) and have XP available through a Virtual Machine Window. Oh there is never enough time it seems. I am also putting together a "Boot Camp" presentation for our local LUGs. Please tell us how it all turned out. I would copy your MBR and first 63 sectors (see the MBR Copy Appendix below), of the XP disk and of the new FC5 disk. Keep these on a CD or flash drive or other reliable place (e-mail?). As others have pointed out machine management SW and antivirus SW tend to take any changes to these as hostile and "repair" without asking. Yes you will need to shut off whatever caused this later but restoring the MBR is easier with copy saved outside the system and helpful to restore one if the MBR is damaged (like maybe by a virus). I think it would be good to have some Live CDs on hand. They are wonderful for working with this kind of thing and tend to save your neck if something goes wrong. I like Puppy Linux because it comes up fast and has usable versions of the basic tools available (although it is often the busybox version which is limited). I like KNOPPIX since it is fairly comprehensive in both tools and very good at finding good hardware configurations. Following are some reference materials from others I have written: Basic Thought: Write down on a sheet of paper exactly what you want to do (large outline) then fill in the outline with specific steps with the exact GUI or command line commands to accomplish that. If there is info on the disk you need, transfer it elsewhere before you start!

During the XP install process you can delete all of your partitions (you will need to fix the MBR to do so - see previous post - or do a "XP fix mbr" in Google and realize that if your system is simple (a C: drive only for XP) then just the "fixmbr" command will work). 2. Reduce the size of the XP partition - see below ("find on page" "ntfs"): http://www.linuxmigration.com/quickref/install/disk.html#ntfs http://mlf.linux.rulez.org/mlf/ezaz/ntfsresize.html GRUB Appendix: Shows techniques to find out how GRUB "sees" the drives attached (was written to an Ubuntu user doing dual boot with XP); First I run grub with no flash drive attached (note the comments about "TAB" in the grub splash text): ------------------------ GNU GRUB version 0.97 (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0, Possible partitions are: Partition num: 0, Filesystem type is ext2fs, partition type 0x83 Partition num: 4, Filesystem type unknown, partition type 0x82 grub> root (hd0, ------------------------ Note that at the first prompt I typed "root (" and THEN hit tab once. The command turned into "grub> root (hd0". I THEN hit the tab key again and it popped up the rest that we see. I then exited grub with "quit" (yes, you MUST do this to see changes!!!). Plugged in my new 1G drive and entered grub again: ----------------------- GNU GRUB version 0.97 (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd Possible disks are: hd0 hd1 grub> root (hd1,0) ----------------------- Note that this time grub found a second "hd1" and that when I had entered "hd1" the next tab yielded "," and the next tab "0)". Grub apparently finds bootable devices and simply lables them incrementally. If I want to make grub form a Master Boot Record for my flash drive then as I use it "right now" (with the drive plugged in this session" I will need to address the writing of that MBR to "hd1". IT WOULD BE USEFUL TO SEE YOUR RESULTS OF DOING THE ABOVE (without the flash drive of course). Grub also sees the partitions "one less (-1) from everybody else.
