Hello everyone, I am trying to do a very specific kind of install, and I am having a lot of trouble achieving success. I have tried to accomplish this numerous ways, and I have searched the net for answers for the past three days, to no avail. I spent the morning searching this particular forum, and still found no answers. Before I start rambling on, let me explain what I am trying to do here. I have an unattended install of Win XP Pro, which I put together myself. I also have a copy of Slackware linux called Back|Track 2. My computer is a Dell Vostro 1000 with one (120GB) harddrive. What I want to do is install XP in three seperate partitions, and Linux on a fourth. Each XP partition needs to be assigned the drive letter [C:] for the purpose of proper installation. Each OS needs to be hidden from every other OS. I do not want to be able to access or modify any partition outside of boot, nor do I want any files or folders to be shared between OS's. I have used Partition Magic to set up my harddrive. I partitioned, formatted, and named each to correspond with the type of install to be placed on it. The partitions appear as follows in Partition Magic: Partition Type Size -------- ----- ---- *:Office ntfs 35GB *:Media ntfs 35GB *:Games ntfs 35GB *: Extended *:Swap Linux swap 2GB *:BackTrack 2 Linux Ext3 7.5GB (All ntfs partitions are now primary, but initially only the Office and the Linux ext3 partitions were set to primary) Now, I haven't even come close to attempting the Linux install, because I am completely stumped on this multiboot XP problem. And that problem is this: I installed my first OS on the C:\ drive, when it was finished, I installed Acronis Disk Director suite v.10, and rebooted. I then installed Acronis OS Selector, and rebooted again. I then proceeded to install my second OS. Now, my unattended install specifies the C:\ drive for most of the software, so when I went to install the second OS(Media), It became flawed, due to the drive letter becoming E:\. The first try was without the C:\(Office) drive being hidden, so All my software was put on that drive. It also appears to have used some of the OS files too, though I'm not sure. I then re-read the documentation on Acronis, and found that I needed to set the partitions to primary, hide the first OS, and set the new partition to active. This is where the problems began to occur. I tried to accomplish this within the OS Selector, but it will not allow me to hide the Office partition. I was able to set the new partition as active, but when I went to install, the installation menu showed two problems, one, the Media partition was still set to inactive, and two, the Office partiton was still showing itself to be C:\. I could not proceed, so I tried a different approach. I booted into Partition Magic, and set media to active, and hid all other drives. This allowed me to install correctly, with the Media OS being registered as C:\. But, since I had hidden Office, I was not able to access it(Office), or Acronis OS Selector until I went back into Partition Magic and set it as active. Doing this, I booted into Office, and needed to re-install OS selector(I believe this is because the Boot Sector was over-written?). Rebooting, I was then able to access Acronis OS Selector, But I could not find the Media OS. No way, no how. I booted into office in an attempt to set the boot.ini file to recognize it. This allowed me to see the option for the media OS in Acronis OS Selector, but when attempting to boot into it, I was taken into Office instead. I believe this may be due to the Media partition being hidden, so I attempted to set it to active, and unhide it. This did not work at all. It seems the only way I could boot into Media, was to use partition magic, and set it to active, unhidden, then hide all other partitions. But this causes Acronis OS Selector to become unavailable, because it is installed on the Office partition. I tried a suggestion I found on this forum, which called for booting into Disk Director from OS Selector, but that simply does nothing. I'm not sure why, either. I have the option in OS Selector's menu, but it just reboots into OS Selector, and nothing else. Due to this, I was unable to proceed with the aforementioned suggestion. Now that I have sufficiently rambled on forever, Let's sum this up, shall we? I need help... please? I could have made the whole thing that simple, but then that would leave you with many more questions than answers, now wouldn't it? Anyway, sorry for the long post, but I really need to figure this out, and I want to leave you with enough info to at least give me an informed answer. So then, does anybody know how I can accomplish this?
