Hello, I am just downloading the FreeBSD 9.0 memstick.img release and preparing myself both spiritually and physically to install it on my laptop. At first I tried thousands of ways to boot the DVD .iso image from a USB device, but nothing worked, so I will install the memstick image from a pendrive and install the complete packages from the DVD .iso file I will mount when the install succeeds. First of all, here are the partitions (on a single 500 GB hard disk): 400 GB, ext4, Installed Linux Ubuntu 12.04. 25 GB, ext4, Installed Backtrack 5 R2. 25 GB, ext4, Here is where I will install FreeBSD. 16 GB, extended. 16 GB, Linux Swap. For now, both OS's are working great, fixed the boot issue Backtrack had, and everything just fine (yep, it was me alone, and therefore just me and no one else than me doin' it :e ). As I mentioned, I will install FreeBSD using a USB boot device, and I expect the install will be quite intuitive, formatting third partition, etc. I will use a method I saw on a thread (http://forums.freebsd.org/showthread.php?t=30136): I am quite new on UNIX/Linux environment, been using for less than half a year, and here comes the annoying questions. Are 25 GB enough for a FreeBSD complete install? The install purpose is educational only, not that I am going to install huge programs/games, etc. Maybe some development and programming... Will the boot configuration going to be screwed (as I was warned)? Do I have to create another partition for a separated SWAP for FreeBSD or it will use the same Linux Swap partition? On long term, will the hard disk become unstable because of implementing so many partitions or filesystems? Is FreeBSD kwnown to have problems with Optimus technology on nVidia Cards? And, if anyone needs to know, the laptop has: IntelÂ® Coreâ„¢ i5-480M 2.66 Ghz (with integrated graphics on itself). Nvidia Geforce GT 540M 1GB (with that badass Optimus technology). 4 GB DDR3. And, if anyone has the divine intention of reading (and even more, responding) I will personally pray for your souls and bless you in the name of the almighty Joe Pesci. Thank you.
