Ubuntu Installation :: Partitioning - Triple Boot With Full Disk Encryption ?

Mar 28, 2011

To structure the layout of my partitions. I'm installing Windows 7, Backtrack 4 R2 and Ubuntu 10.10 Desktop on my laptop. I've got a 500 GB HDD named sda.

I've already installed Windows 7. It's my opinion that it's easiest to begin with Windows.

The partitions look like this right now:

The Windows installation is unencrypted and I want it to stay that way. It's only there in case my laptop gets stolen, I've installed various nasty things there.

The Backtrack 4 installation will also be given 100 GB space, I want it to be encrypted. The Ubuntu installation should get the rest of all the remaining space and preferably be encrypted but it's not 100% necessary.

How I should partition this? There's a limit on 4 primary partitions? How do I circumvent this? There should be one dedicated GRUB partition which will point to each of the installations own boot loaders?

Ubuntu Installation :: Separate Boot Partition - Doesn't Care About The Boot Flag On The Disk

Feb 14, 2010

GNU GRUB 0.97
Ubuntu 8.04.4
2.6.24-26

Added an SSD (dev/sdc) and decided to move some less often changed directories there. Started with /usr and /boot, leaving / on a primary in the first drive, for now. All started ok, and my changed fstab mounted the right ones, and the system works.

However, grub is actually using the original /boot on / on sda1. I cannot see any way to change this. (Which makes it sorta hard to update the kernel

From grub:

Okay, since it has two choices, I tried to tell it which one to use. But, grub> root (hd2,5) does nothing.

Disk /dev/sda:

what I seem to recall, grub doesn't care about the boot flag on the disk. Nor does it care about primary vs. logical (except GNU doc says "makeactive" only works on a primary?).

The GNU doc also indicates that it looks for a directory /boot on the partition, so if you're mounting a partition as /boot, it also needs to contain a /boot directory under it. Tried that, but no change.

Is my problem the logical partition? Does that prevent "grub> root" from changing it? I'm afraid to wipe out the old /boot and find that I can't start up.

Ubuntu Installation :: Partitioning For Dual Boot-- Windows Is On An Extended Partition - Other Weirdness??

Jan 9, 2011

I successfully partitioned my desktop with Gparted and made it into an XP/Ubuntu dual boot.

Now i'm trying to do the same with my netbook (eee pc 1000he), and the existing partitions look funny:

How should I change this to prepare for installing Ubuntu? Can I just install to the unallocated space on the extended partition? I don't need optimal efficiency here, I just need to know where to install Ubuntu for a workable dual boot.

It's confusing to me that Windows is on an extended partition, and also that /dev/sda2 has the boot flag (this drive contains nothing but two undeletable folders titled "amd 64" and "i386"). This set-up is the result of a Windows re-install at a sketchy computer shop.

CentOS 5 :: Partitioning Error - Dual Boot With Win7

Sep 23, 2010

I have a problem trying to install CentOS 5 as a dual-boot with my Windows 7. Using Windows tools, I shrunk my main partition and created about a 100GB of unallocated free space. Then, I restarted my computer, booting from the CentOS dvd, but when choosing "Use free space on selected drives and create default layout" option during installation, I get an error saying that partitions couldn't be allocated as primary partitions and that there is not enough space left to create partition for /boot.

Ubuntu Installation :: Dual Boot Partitioning \ What File System Should Use For Windows Swap Partition

Sep 1, 2011

I am about to get a new laptop here soon and I was planning a dual boot like I have on my current laptop (Win7 and Ubuntu), but I have something special in mind. I looked around the forum to see if there was anything like what I had or if it was even possible but I didn't see anything quite like this.I was wondering if this was even possible, and if so, would anyone be able to tell me what filesystem I should use for my windows swap partition?

CentOS 5 :: GPT Partition Scheme On HP ProLiant DL180 Server

May 12, 2011

I'm installing Centos 5.5 on a HP ProLiant DL180 Server with ~8 TB of hard disk (4 disks that have been pre-RAIDED), from an installation DVD.

Normally when I get to the partitions screen, I would select "remove all partitions etc".

But this gives me an error message "Your boot partition is on a disk using the GPT partition scheme but this machine cannot boot using GPT. This can happen if there is not enough space on your drives for the installation."

Pressed OK, tried the other three partition options but they led to the same outcome.

Tried Advanced storage configuration: Showed that there was one hard drive (c0d0) with ~ 8 TB of space.

I figured I should create a root sector, set one up with 100 MB of space, ext3, set the mount point as /.

Created a software raid of the remaining space.

Trying to go "next" gave me a similar error about GPT partition scheme. Trying various other configurations all gave similar errors about the GPT scheme.

What do I need to do? Some earlier hard format of the disk or something?

Debian Installation :: Partitioning Scheme For GPT On A SSD

Sep 23, 2014

I have a Intel DH67CL motherboard with UEFI support(and updated to latest BIOS). I have connected a 180GB Intel 330 SSD into my system so as to install Debian testing.

Presently, a 160GB sata hard drive is connected along with SSD and is used to boot default OS.

1. I am planning to do GPT partitioning. I am totally new to GPT partitioning. from what I understands, It needs some mandatory partitions like ESP. My doubt is, in a SSD solely booting Linux, will I need to create separate /(root) and /home and /data partitions? Also, I plan to use /var/log and some other frequently updated directories moved into existing harddrive.

So, what is the partitioning order - is this fine - ESP(512MB), /boot(100MB), /(30GB), /home(50GB) and /DATA(50GB) and remaining 16-17GB for over provisioning for the SSD?

2. is there a need to have 128MB MSR(microsoft reserved) in the case of Linux

3. With gdisk or parted for creating partitions? how to verify if partitions are aligned. In GPT, only primary partitions are supported?

4. Some answers in askubuntu/superuser says ext4 is not really good for SSD, instead take JFS? is this true? Is Btrfs mature enough to use with Desktop system

5. Which bootloader? gdisk creator Roderick is pushing for rEFInd or gummyboot instead of GRUB2.

6. In my PC, 4GB RAM is available with a core i3 processor. Shall I mount /tmp in RAM? Will I need to specify the size of RAM when mounting using /etc/fstab? A size of 1GB is fine?

7. using deadline I/O Scheduler instead of CFQ?

OpenSUSE Install :: 11.2 On An Existing Partitioning Scheme With Encrypted LVM

Apr 5, 2011

I have a Ubuntu server with encrypted LVM2 (logical volumes - /, /var,/tmp,/home etc.). I need to migrate this to an OpenSUSE 11.2 server (cannot use a later version due to the availability of a binary-only module - that is just the way it is). When I fire up the installer, I cannot seem to find an option to mount the encrypted disk (/dev/sda) which has the LVM2 structure. I do not want to lose /home (logical LVM2 volume), so a clean blank slate install is not an option.

Ubuntu :: Install - Disk Partition Effective But No Boot?

Feb 16, 2010

I just installed Ubuntu on my laptop (x200s, XPpro with 230 Gb), and created a 30Gb partition therefore. At the end of the install, the screen remained orange for a while, without any disk activity. I forced the laptot to reboot, but Ubntu was no option when the machine restarted. However, my XP partition has been reduced by 30 Gb. Does anybody have an idea about what I should do to either get Ubuntu installed or recover the disk space?

Software :: Possible To Boot From Hard Disk Having RAID Partition?

Mar 28, 2010

I wanted to implement raid5 such that one partition is from my laptop's hard disk and others from other hard disks. After making one partition a raid partition, I rebooted the system. The computer stopped mid-way during booting, and brought me to the shell. On typing fsck -p, it told me an unexpected error occured in the partition which I had made for raid. Is there some condition that we cannot boot from a disk containing one of the raid partitions ?

General :: Copy DVD ISO To Empty Hard Disk / Partition And Boot As If It Is A DVD?

Sep 10, 2011

I have a broken DVD drive and no others available right now to burn a DVD iso to so I'd like to use a empty hard disk instead.

I've tried Unetbootin but that only copies a few megabytes of files - the rest of the image data in the ISO is ignored.

I have verified the ISO is valid and working with VirtualBox. It's MD5 hash is also as expected. But I need to boot at the real bios not an emulated one.

I've also tried things like:

sudo cat /disk/image.iso > /dev/sdb1

and that got "Permission denied" -

Ubuntu Installation :: Dual Boot - Mandriva - How To Partition My Disk?

Feb 26, 2010

I recently made the move from windows to Linux and I am happy to having got rid off all the MS stuff. Trying out a few distros I decided on using Ubuntu and Mandriva (wife likes the flashier stuff, what can I say ).

My question is how can I partition my hard disk in such a way that my /home is separate from both the Ubuntu and Mandriva part but accessed by both as my default home folder.

CentOS 5 :: Trying To Boot From Disk With New ISO

Oct 25, 2009

I'm trying to create several Centos virtual machines to run Cpanel servers on each. Centos 5 looks good due to bundled Xen. Not sure whether to go for 64 bit version of Centos 5 and run some of the Apps as 32 bit and a few as 64. The h/w is a Dell poweredge R710 with dual 2.26 GHz quad core Xeon procs, 5.86 GT/s 24GB ram memory speed 1067 MHz. Raid with perc 6/i.

I burned the Centos 5 iso onto cd-rw but my lap top and the new dell won't boot from it. I viewed the readme file which seems to suggest burning "boot.iso" on its own but that doesn't work either. A boot menu on the Dell has an option to "Deploy" an O/S. Do I need that or can't I simply boot from cd-rw? I used Nero to burn the cds. I asked Nero if any special box needs to be ticked to write a bootable image and they said no.

Ubuntu :: Partition Table Damaged - Pc Doesn't Boot From Hard Disk

Feb 20, 2011

Caused by Used fdisk to delete the windows partition, in my dual boot. Then I could no longer log in to ubuntu, the partition table was some how courpt and I couldnt remount I then decided to use the windows partitioner from windows setup, as I thought it is so stupid, to reformat the partition where I had ubuntu. I wanted reinstall ubuntu, and I know that during the setup I could straighten out the mess I'd made.

Windows has now installed two 8mb one cylinder partitions on my HD. When I start the PC I get a !disk error occurred Press Crlt Alt Del to restart! This happens everytime. HD boot sequence is buggered, i guess.

I can boot from other devices. USB + CD. How when I use the windows disk to boot up I can see the 2 8mb partition, which it wont let me delete. How can I delete this via linux?

Also when I try to install ubuntu from the usb drive, it stalls just after the Preparing to install part. The next screen is when you set the partition table, swap drive etc. When I quit I get the following error !Process Glib WARNING getpuuid_r() failed due to unknown id!

The usb_liveCD does however mount my hard disk partitions and luckily I have managed to back everything up to an external.

Installation :: Dual CentOS - Windows 7 Boot - Had To Delete CentOS Partition And No Grub Menu

Sep 19, 2010

3 partitions (in order): Windows 7, CentOS and shared data partition.

I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).

GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).

Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.

Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?

CentOS 5 :: Resizing CentOS Boot Partition, Dual-booting?

Jun 9, 2009

I have a laptop that came with Windows Vista (64-bit) installed. I created a new partition and installed XP (also 64-bit) alongside it.Last night I shrunk my XP partition and created another new partition and installed Linux (CentOS 64-bit) on it. I made an error in judgment and didn't allocate enough space, so I need about 10 more gigs for the Linux partition. It boots up and runs, but I need about 10 more gigs of storage for the files I want to keep on the partition (and yes, they have to be on the partition, I definitely need to know how to do this, not a workaround)I went into Vista and shrunk the XP partition by 10 gigs, so now I have 10 gigs of free, non-partitioned space.

As it stands, when I start up the computer I get the GRUB boot loader. I can boot my Linux install or choose "Other" and be taken to the Vista boot loader. From there I can choose XP or Vista to boot.So, my question is... what is the best way to append the 10 gigs of free space to the Linux partition? Is this something I should do inside of Linux? I have the option to do it in Vista, but the partition shows up as "healthy" but without a file system type.I just don't want to screw up the boot loader, partitions or anything else.This isn't my area of expertise, so if anyone could give me a good suggestion or solid answer

Ubuntu Installation :: Partition By Default - How Much Disk Space A Non Manual Dual Boot Uses

Apr 23, 2010

how much disk space a non manual dual boot uses? I've always been guided by a person knowing much about linux when doing my dual boot (and been guided to do the partitions manualy), but this person is not there for the moment and I need to do a dual boot on my son's computer. Since he'll need his Windows computer mainly for games I wouldn't want Ubuntu to take 2/3 of his disk space (which is about 250 Gb I think, let's say 50 Gb would be perfect for the Ubuntu)

And I'm not sure how I could change this later, cause in my own computer I cannot find how to resize (I cannot unmount neither resize the partitions I have) I don't mean I need to do this on my computer but I mean I wouldn't want to try out anything if I'm not sure it be could restored in 1,2,3. And partitions is such a thing. If I remember correctly I've done dual boot by default (i mean without doing the partitions manualy) and it does about 50/50 ?

CentOS 5 :: Using USB Flash Stick As Boot Disk

I will have Windows 7 as Drive 1 and Linux as Drive 2.I would like to not touch Drive 1 at all NO grub or other boot-loader. My old system I used a floppy drive as a boot disk.This worked if floppy was inserted: It booted grub giving me the choice of Windows(drive 1)or Linux(drive 2). I would like to replace the floppy with a USB stick. I have a couple of 64 MB (LOL) flash drives to use.

Ubuntu :: Hibernation On Windows 7 Dual Boot - Under Disk Utility Partition Is Not Marked As Bootable

Sep 29, 2010

I have been having problems hibernating my windows 7 partition recently. It happened approximately right after I set up the dual boot.

I have found other topics where it says to make sure that the windows 7 partition is marked as the active partition. I have since done so and it has not changed anything. I did it with Partition Magic on Windows. I did find it suspicious though that my Dell Recovery partition is labeled as boot while the Windows one is marked as Active and System.

However when I looked at it using disk utility in Ubuntu the windows 7 partition is marked as Bootable while the recovery partition is not.

Hibernation works on Ubuntu with a couple error messages while shutting down and some weird screen issues while booting up. But it ends up working decently.

Under Disk Utility the Ubuntu Partition is not marked as Bootable. Should it be?

CentOS 5 :: How To Boot 5.3 From GPT Partition

Jun 2, 2010

My hardware: HP ProLiant DL 180 G5 5x750GB SATA drives, HP Smart Array P400. Array configuration: 4*750 + 1 spare in RAID 5 (more that 2 TB). I have to install CentOS to this machine. After many unsuccessfull attempt I think that CentOS 5.3(or later) have no way to install on a GPT partition with /boot on GPT device. While installing at the moment of writing partitions information to disk anaconda returning following error: "Your boot partition is on a disk using the GPT partitioning scheme, but this machine cannot boot using GPT".

By the way, with RHEL 5.3 situation the same. Only Fedora 11 can install, but only after creating 1 small partion (fro /boot) in parted, clicking back and clicking next 0_o (in clean array cause, without any partitions). Now I installed CentOS 5.3 by this way: I created two partitions my array volume: small 256 MB for future /boot and big lvm for rest. Then I created small partition on usb-attached drive an used hem to /boot.

[root@backup ~]# parted /dev/cciss/c0d0 print
Model: Compaq Smart Array (cpqarray)
Disk /dev/cciss/c0d0: 2250GB
Sector size (logical/physical): 512B/512B

[code]....

Now I want to install grub to /dev/cciss/c0d0p1 (small first partition on array), for booting true from array, without any usb-drives etc. Also after googling I found that 2.6.18 (all kernel later that 2.6.25) kernel and grub 0.97 not supporting GPT. Can anyone confirm it? I installed the Fedora 11 to this server, she have 2.6.29 kernel and grub 0.97-50 (0.97-13.2 in CentOS). I have to download and compile a new kernel, download and install a new grub?
