Q1) I was wondering if it is possible to Dual boot Ubuntu with Windows XP on a 1TB RAID-0 setup ?
Q2) Also, is it possible to create a SWAP partition (for Ubuntu) on a NON RAID-0 HDD ?
Q3) Lastly... I read GRUB2 is the default boot manager... should I use that, or GRUB / Lio ?
I have a total of 3 HDDs on this system:
-- 2x 500GB WDD HDDs (non-advanced format) ... RAID-0 setup
-- 1x 320GB WDD HDD (non RAID setup)
(The non RAID HDD is intended to be a SWAP drive for both XP and Ubuntu = 2 partitions)
I plan on making multiple partitions... and reserve partition space for Ubuntu (of course).
I have the latest version of the LiveCD created already.
Q4) Do I need the Alternate CD for this setup?
I plan on installing XP before Ubuntu.
This is my 1st time dual booting XP with Ubuntu.
I'm using these as my resources:
- [url]
- [url]
Q5) Anything else I should be aware of (possible issues during install)?
Q6) Lastly... is there anything like the AHCI (advanced host controller interface) like in Windows for Ubuntu?
(Since I need a special floppy during Windows Install...) I want to be able to use the Advanced Queuing capabilities of my SATA drives in Ubuntu.
I wonder whether to place swap partition on LVM or on standard fdisk partition which will not be in LVM.What is better and more often used on production ?

I'm installing the ubuntu on my new computer with 1 TB hard drive (and core i7 870 with 4G RAM), for the purpose of scientific computing. I have two questions:
1. Since I am not absolutely certain that the simulation won't use larger swap space than usual (say 3x4G = 12G), I intend to set it initially as 12G keeping in mind that I might have to extend it later. So one might suggest putting it on lvm partition. But then I read that I can maximize the speed if I put the swap at the outer track. If I mix it with the other logical volumes in the same volume group, then I don't know where my swap space is across my hard drive, isn't it? So this might suggest I make it as a primary partition. I'm stuck..
2. My current planned partition map is
/ 1G
/tmp 10G
/usr 20G
/var 5G
/home the rest
taking into account I will install MATLAB and maybe other visualization software. What do you think of this scheme?
during my fedora 12 installation, i made a swap partition by the wrong denotion "/swap".so when i had used the command "df -h",it showed the /swap entry in the list.so i deleted that particular partition using the "parted" utility. Now my doubt is, 1.where is that partition?(whether it has joined with other partition or still alive) 2.if it alives,is it possible to make it as a swap partition?

View 1 Replies View RelatedSomeone (not me) recently installed some new distros on my HD. It seems that during the installation my swap partition was reformatted and a new UUID was assigned to it. I have the following questions:
1. I know that I have to change the swap partition UUID in /etc/fstab and /boot/grub/menu.lst of the affected distros. Is there anything else that needs to be changed?
2. I presume a similar change has to be made to the Grub 2 configuration, for those distros that use Grub 2. I have no experience using Grub 2 so how do I make the change or where can I find instructions to do it?
As far as I know hard drives are faster at the beginning of the disk. If this is true, why does Ubuntu put the swap partition to the back of the disk by default?
View 1 Replies View RelatedWhen I do a "clean" install of Ubuntu 9.10, Step 5 of 7 is when you choose how to partition your hard drive. My Acer Aspire Desktop has 8GB of RAM and a single 160GB SATA hard drive. If I choose to let Ubuntu do the partitioning, only three partitions are created and one of them IS a Swap partition. However, if I choose the second option to manually create my own partition tables, there is NO Swap option listed in the drop-down list of partitions to create!! Why in the world not, considering the importance of this partition and the fact that the first option DOES automatically create it? A second related (I think) is about the Live System Rescue CD and GParted 4.9. When do you use either of these utilities? After all, GParted is included System Rescue CD.
So, if I want and choose to do a manual/advanced partitioning of my hdd, the only time I can see using either utility is after the complete installation of the Ubuntu distro. Yet, choosing to manually partition my hard drive always results in an error or warning message that I haven't created a Swap partition before proceeding to Step 6 of the installation. Well, of course not since the choice isn't even possible. Good grief, what am I supposed to do when I arrive at the step where I am supposed to choose and then create the partitions for my hdd? Choose the first option, which I don't think is wise/good at all, especially with security in mind. Or choose the second option of using a program like GParted at all? It is hard enough for me to choose a partitioning scheme at all, since opinions on how many partitions are needed and what sizes they should be.
There is a Swap Partition Error when I am installing ubuntu. I have two options now.

(2) Change to another distro. I am looking at Ubuntu, Fedora, Mint and Mandiva now. Which one do you suggest?
I'm triple booting Windows 7 32-bit (that's the only version I had), Ubuntu 10.10 64-bit, and Backtrack 4 R1.
Windows 7 installed and runs fine. Ubuntu installed and runs fine. I try to install Backtrack 4 R1, create a / partition, create a /boot partition (do I need to create a /boot for Backtrack?), and I don't create a swap file because the Ubuntu swap file is already in there.
I click "forward", the install starts up, then I get "The attempt to mount a file system with type swap...yadda yadda yadda...has failed." I google this, I get some results talking about an mkswap command, but in my noobness, I don't understand.
Can Ubuntu 64 bit and Backtrack not share a swap file? I don't want to create 2 swap files because I've googled around and that looks like a bad thing to do.
why is a swap partition a requirement for a linux setup? What arguments would you use to decide on the size of the partition?

I had a drive with a partition layout like so:
~50gig Windows 7 - NTFS
~100gig Ubuntu - EXT3
~100gig Snow Leopard - HFS+
~100gig Extended Partition
-- ~100gig Swap Disk - exFat
I wanted to delete the Snow Leopard partition and format the Swap Disk partition to something else. exFat was causing major file size bloat on small files. QT sdk bloated to like 11 gigs or something ridiculous like that. Anyways, I loaded up an Ubuntu 10.04 LTS live cd and gparted then deleted the Snow Leopard partition. Gparted said "Mission Accomplished" and tried to rescan the drive, but never found it. At this point I restarted the computer, a dell laptop, which didn't boot with an unable to find a bootable device error. The ubuntu live cd doesn't see the drive anymore. gparted scans for drives indefinitely and fdisk -l has no output.
I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?
I am having issues with Grub 2 after installing Debian 7.8.0.The computer is a HP Pavilion 500-307nb. I made the original harddrive /dev/sdb and inserted a Samsung Evo 840 as /dev/sda. From the original hard drive (/dev/sdb), I wiped the windows partition, but left all other partitions unchanged (in case I would ever want to recover the desktop to its original state). I replaced the wiped windows partition with a swap partition and an LVM partition.These are my hard drive partitions:
/dev/sda (Samsung Evo 840)
Number Start End Size File system Name Flags
1 1049kB 3146kB 2097kB primary bios_grub
2 3146kB 944MB 941MB ext4 boot
3 944MB 94.4GB 93.4GB host lvm
4 94.4GB 1000GB 906GB guests lvm
[code]....
The partition /dev/sda3 has 2 logical volumes with filesystem ext4 that I mount to / and /home.The partition /dev/sda2 is mounted to /boot..When I install like this, Debian installs fine, however Grub2 is not installed correctly.Debian installs grub-pc which seems not able to boot the gpt partition. So I boot the Debian CD in rescue mode and execute:
mount /dev/sda2 /boot
aptitude purge grub-pc
aptitude -y install grub-efi
After rebooting, I come in the grub rescue shell, which says: error: no such device: 986f2176--4a4b-4222-83b9-8636a034b3c7.
When I then enter in the grub rescue shell:
set boot=(hd0,gpt2)
set prefix=(hd0,gpt2)/grub
insmod normal
normal
Grub and Debian start up correctly.why can Grub not start up automatically correctly? Where does the UUID 986f2176--4a4b-4222-83b9-8636a034b3c7 come from? I have reinstalled Grub several times, I have reinstall Debian several times, I have even wiped all partitions from /dev/sda and recreated a new gpt table with parted and manually set the partitions in parted. Still on each reinstallation, Grub fails because it cannot find exactly the same UUID. Since this UUID is always the same, it must be stored somewhere, but it cannot be the partitions, I have wiped them and the partition table several times.
I did though a firmware update of the Samsung Evo 840 before reinstallation, could this be a cause?Also the problem is not in grub.cfg. Grub starts correctly if I enter the commands above in the grub rescue screen and the UUID value does not appear there.
I've recently just installed ubuntu 11.04 but seem to have made a big mistake. During the install process I was asked to specify a location to be used for swap. Not really understanding what this meant I chose another partition on my drive with some free space but also a lot of my data. Needless to say I now cant see that partition. Is there anyway for me to access it? or to at least recover the information I need from there? its about a 200gig partition, and it used to be ntfs.
