[indentation recovered] Hi Piyush, Jud wrote: I can think of two alternatives. (There may well be others.) The first is to delete the DOS logical partition either with DOS fdisk or with a utility such as Partition Magic or the (cheaper and IMO excellent) BootitNG from TeraByte Unlimited. Then using the partitioning utility, resize the extended partition to leave room for your FreeBSD install.

Beginning Free space Outside _ Mb(we are supposed to fill in the size in Mb...) Free space Inside_ Mb End Free space Outside _ Mb Free space Inside_ Mb .the problem is that I don't want to experiment cause ..I don't want to lose any data. and also that I'm not sure on what exactly to do...if you'd just tell me how to go about doing this I'd be grateful O.k., when I answered your question, I assumed you already have a working Linux installed. Seems this is wrong. I can't help you with bootit and I wouldn`t trust its calculation from MB to disk block numbers as long as there is no possibility to check them exactly. If this program decides to calculate this numbers wrong (think of the MB=1024 kB or MB=1000kB problem) you endanger your information on partition f: . If you want to be sure either get more information about bootit or go the Linux way, by just downloading a mini-Linux (http://www.toms.net/rb/) on a single diskette. This is all you need to do the steps I described in my previous mail. Don`t hesitate to ask again, this is a dangerous area.

Re: Installing on a logical DOS partition
Hi Piyusch, Piyush wrote: The program shows the primary dos partition and extended dos partition but not any logical partitions under the extended partition..the logical partition on which I wish to install Fbsd is the last one...if I delete a 'slice' of a particular size will fbsd delete any other partitions? Jud wrote: The second alternative might work if you have Linux handy and it groks Windows logical and extended partitions (I don't know anything about Linux). Try deleting the DOS partition, changing it to a Linux partition, and see if FreeBSD understands it. If it does, install there. This way will work, but be very careful, you are operating on the heart of your hard disk management. So if you have any precious data on this disk: Backup first, make sure you can retrieve your data from these backups! So then in Linux call your fdisk like: fdisk /dev/hda change the display of the units with the u command as it is easier to handle LBA block numbers than CHS numbers. Type p and write down all the numbers. This will enable you to restore the state of your hard disk, if anything goes wrong. Changing the MBR doesn`t actually destroy your data, but can make it impossilbe to access it anymore. If you exactly restore the information you just wrote down, it is possible to regain access. You were lucky so far, as the partition you want to use is the last in your extended partition. This makes it easy to reduce the size of the extended partition and reuse the gained space for a primary partition. So if your layout is for example like: primary partition 1: LBA 1 - LBA 1 extended partition: LBA 1 - LBA 4 logical partition 1: LBA 1- LBA 2 logical partition 2: LBA 2- LBA 3 logical partition 3: LBA 3- LBA 4 Maybe the beginning of logical partition 1 is actually on 10001 (one block needed to write the EMBR), but this is not important. Just use the numbers as you have them now. Now you want to use logical partition 2 then you have to get to the following layout: primary partition 1: LBA 1 - LBA 1 extended partition: LBA 1 - LBA 3 logical partition 1: LBA 1- LBA 2 logical partition 2: LBA 2- LBA 3 primary partition 2: LBA 3- LBA 4 You get the idea? So the first thing is to delete logical partition 3 (Linux fdisk would probably show this as partition 7). Then you have to resize the extended partition, i.e. adjusting the end block from 4 to 3. I don't know, if Linux fdisk will allow this directly or if you have to delete all the logical and extended partitions first and then recreate them with the correct numbers. Just try, there will be no harm, if you just quit the fdisk with q. Only if you hit w the changes are actually written to disk! If you have the correct values for the extended partition and logical partition 1 and 2 create a new primary partition 2 with n and give it all the available space you just freed by deleting logical partition 3. To be sure you can change the type to FreeBSD, but I believe FreeBSD sysinstall will recognize the primary partition independent of its type. So it should be possible to install FreeBSD there now. If what I wrote is not clear to you, ask first before dong dumb things. Maybe this is a good time to pay your local guru a beer to accompany your steps. :-) BTW, it is possible to use logical partitions as FreeBSD mount devices, but you have to do all the magic by hand, as the tools don`t support this. And final note: In FreeBSD DOS/Linux partitions are called slices. Such a slice is then separated into FreeBSD partitions (no DOS/Linux equivalent exists) with sysinstall. FreeBSD partition c is the complete disk, a ist the partition which contains the / mount point, b is swap space. So you can use d and up for /var, /usr, ... mount points, if you want.

Installing on a logical DOS partition
Hi, I have a logical DOS partition(e:),on which I wanted to install FREE-BSD,I didn't know how to go about selecting this partition as the partition on which I wish to install FREE-BSD during the install process,can you please tell me how I could do this or any resource which(on the WEB) would help me on this front. Thanx in advance, Piyush

Jud _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ My apologies, Piyush, I may have steered you wrong. I failed to take sufficient note of the fact that you're speaking of *logical* DOS partitions. Start the install (you can cancel out of it) and see if the DOS partition is shown in the list of slices/partitions. If it is, you're good to go. If not, them I'm afraid you'd need to do some reworking of your partitions/slices with a program like Partition Magic or (less expensive but IMHO excellent) BootitNG from Terabyte Unlimited.
