Ubuntu :: Booting From USB Disk Installation
Apr 9, 2011
I'm having trouble using Ubuntu 10.10 (64 bit) to create an installation on a USB (read-write) drive. I've had to use PLOP to boot the system, since I want the usb drive on a high-speed controller, and my machine is such that the on-mainboard USB is slow. So, I put the empty USB (16 GB) on the fast controller, boot from the Ubuntu installation DVD, and install the OS.
Then I switch to booting PLOP, the boot manager, and use it to boot from USB. Everthing works fine, and I can use ubuntu -- but only the first time. Once I shut down, and try to boot again, PLOP doesn't start the boot from the USB drive. It apparently crashes (the star field simulator doesn't continue). It does try to (at least) load the USB drivers, but stalls without finding the USB boot medium (my flash drive).
Anyone have any idea what's happening? Also let me know if there might be a more trusted way to boot from the high-speed USB drive (like, it would be great if the installation disk had an option to install the USB drivers and then do a secondary boot). Plop is nice because it can be on read-only storage (a DVD or CD) and
so can't be corrupted after the fact.

I am a ubuntu user and I tried to install ubuntu on my sister's netbook too. The problem is that the netbook has a broadcom wi-fi n that is not supported by linux for now because I searched for drivers and other stuff an I found that it is not supported. After that I tried to format the disk and reinstall windows 7 but the problem is that the installation procedure gives me this error: "windows cannot be installed on this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enable in the computer's bios menu."
I tried to do all the things that are described here: [URL] but it's still not working.
Obviously when I format the drive with ubuntu and I put it in the netbook it's not working, it stops at the logo and the only thing I can do is entering BIOS.
I formated the drive with a windows os and then the pc makes the boot from usb but the problem persit...I still can't install because of that error :"windows cannot be installed on this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enable in the computer's bios menu."
Before installing ubuntu the sistem had kaspersky antivirus and detected 1 Trojan, it could be that a virus destroyed the bootsect...I don't think so.

My dual proc, dual core Opteron MSI Master2FAR motherboard failed, and I try to boot a disk, used on this board as boot disk, on an Intel based Gigabyte GA-965-DS3. Both systems are x86_64 architecture.
The OS is on both systems is openSUSE 11.1.
On booting the disk on the Gigabyte, the disk is seen correctly by the BIOS, but not by the OS, and there is no /dev/sdX; no /dev/disk/... either. I am taken to a login shell from the ramdisk.
When I just mount this disk on the Gigabyte (booted with the Gigabyte's original boot disk) everything seems fine. No suprise to me, since the disk was fine, and was unmounted gracefully and physically taken off the MSI before the board failed.
I think that the cause lies in the fact that the harddisk controller on the Gigabyte is different from the MSI, and the driver for that controller is not available at boot time.
I have two questions:
- is my assumption correct, or is something else going on?
- if I am right, is there a way to get this disk booting on the Gigabyte (or on another system, for that matter)?
You might want to ask why I want to boot this disk on the Gigabyte in the first place, since I can mount it and see all data on it. I have a reason for that, but telling that story would make this topic too long, and it's too off-topic. Most certainly I will get to that in another topic.

I'm trying to boot Ubuntu from a CD on a Windows XP Home laptop. The CD was burned correctly; i saw all the files on the disk. I restarted the laptop with the disk installed and all I'm getting is a screen that says Ubuntu with five flashing dots in sequence. Nothing else. It has been running for more than 10 minutes now like this.

Is there any way of being able to access data/files from a disk with Ubuntu operating system on it with another disk running Ubuntu? Don't worry, I'll give an example of what I mean, haha. For example, I used to use hard disk 1 as my main drive with the Ubuntu operating system on it. I removed that drive a long time ago and am now using hard disk 2 with Ubuntu on it. Is there any way that I can just retrieve files from hard disk 1 without having to boot into it, ie, treat hard disk 1 like a data drive and be able to copy and paste files from there onto my now main drive, hard disk 2?
If possible, would the process be more complicated if hard disk 1 used a password to log in?

i decided to install ubuntu in my PC,i downloaded the .ISO image and i installed it in my USB. After trying it and all that i observed that i really liked it and i decided to formally install it to my computer in the hard drive. When i reached the partition thing,i selected to dual boot with Vista and select between each them in every startup,when i clicked FORWARD it gave me an error which i did not read(because,again im a noob) so i clicked cancel.
Today i wanted to go through the process again and now really install it,so again i went to the time zone part and i clicked forward but then,instead of taking me straight to the partition phase,it appeard a window saying "The installer has detected that the following disks have mounted partitions: /dev/sda ...." I clicked yes,to unmount this partitions so it took me to the partition thing,once there i selected the option to install Ubuntu with Vista and select between them i neach startup,then i clicked forward and went to the username/computer name process,once i finished i continued to the next part,the installation,but i selected to import all of my WIndows VIsta default user data,after that i clicked forward and went to the installation process,i went down stairs to eat soemthing while it finishes,i came back and it was finished,it asked me to reboot so i clicked in Restart Now.
When it tried to boot,appeared an error saying: Error: no such devide found: #################### Grub load(or something like that) grub rescue: and it was a command line,since there i havent been able to boot into vista or Ubuntu,im really scared because is the first thing related to OS installing ive done,so i booted my USB and ran the trial and right now im trying to find out what to do from that trial version.
I just went to the INSTALL UBUNTU 10.04 LTS application under the System>Administration Menu and found out that in the partition phase the Install and allow to select between both systems in eahc startup option,i dont know what to do,i foudn out that my HD has still all its data(MUsic/Videos/Folders/Programs/ect.)its just that i cannot boot from it. Also in GParted it appears as /dev/sda1/ and a warning icon besides it,also when i go into information, thers this warning there [URL]

I have a working dell deminsions, no problems 2gb of ram, all that good stuff running xp.I have an older HP Pavilion with about 1Gb of ram, running windows 98. There were some issues with the partitions and registries and i want to install Linux over it to fix all issues and make it a working computer again.I burnt the ISO as an image on a cd using, Nero. no problems with the cd. I could not get the Hp to recognize the cd, and it wont boot. So i took the HDD out of the HP and put it into my dell. I can get to the Install part of the setup and that's where it goes to just a black screen with a flashing cursor.I am considering, booting to XP and reformatting the disk, and trying to install it using the HP again.

I want to install a minimal version of linux (probably oS 11.4) onto a partitioned 1TB USB drive to serve as a standalone, bootable restore mechanism for a couple of machines.
First off, is this feasible?
Second, how do I go about it? I was able to install the system to the drive but how do I make that drive bootable? So far, I can't even get it to boot from the grub menu on the first internal hard drive as the system complains loudly about not being able to read disk descriptors and such. I tried the various boot spec (chainloader, menulist, etc) with no luck. Do I need to disconnect all the internal drives then install as if it were the only hard drive in the machine with the DVD reader?
I am assuming that I need some sort of bootstrap code in the MBR of the USB drive to get started but I'm a bit lost here and would appreciate any input, especially from some one who has tried this, before I spend anymore time on it.

I'm trying to get it on my own computer at home to work on. I have an iMac, and I also have a disc with Fedora on it (along with sabayon and slax and a few others). I tried booting my computer from the disc, but when I got to the localhost login bit, I couldn't get any further. I have searched for this query already, but seemingly all the answers assume that it was installed beforehand. I haven't installed anything, just put in the disc and changed the settings to 'boot from disc' before restarting the computer. Am I missing something? Also as a separate query, how do I partition the hard drive so I can run Fedora alongside Leopard? And what is the story with virtual machines?

For various reasons, when I installed our server, I configured it so that it would boot off a USB flash disk. The flash disk mounts as /boot and / mounts on our RAID array.
It all works very well, but I would like to have backup so that if/when the flash disk goes, I can pop in another one.
I have tried to make copies of the flash disk (using both cp and dd), but it doesn't work. When the server starts its bootup sequence, instead of Linux loading, a cursor starts blinking endlessly.
If I put the original flash in, it works fine. If I put the copy in, it doesn't work.
I can't see any difference between the copy and the original. They seem to have the same content. If I do blkid both have the same label and UUID. The label is /boot, and /etc/fstab refers to this
We are running Scientific Linux 5.4.

I have 2 IDE drives, Windows XP is on the Master drive & Fedora 12 is on a partition the other drive. I purposely installed the Linux boot loader on the same drive as Fedora because want to use NTLDR as the primary boot loader. According to a guide I found [URL], I should be able to copy the Linux boot sector to a file & put that copy on the Windows drive & then modify boot.ini, so I am prompted to with an OS choice a startup.
The problem is the command the guide gives to copy the Linux boot sector (dd if=/dev/hdb1 of=bootsect.lnx size=512 count=1) has outdated syntax and does not work. What syntax would make this command work in Fedora 12? Another guide I found ([URL]-vista-already) suggested using: Grub4Dos & modifying boot.ini. This method almost worked until grub gave an error that there was no kernel loaded. What would I type into the grub prompt to load the kernel? How would I automate the loading of the kernel, so I don't have to specify the kernel each time?

I want a debian server running dhcp/tftp/pxe containing a tarball of a 'client' debian installation.I want a client that pxe boots, talks to the server, creates a ramdisk, untars the 'client' tarball to the ramdisk and boots into it. Once that's working, I want an NFS map back to the server for the users home directory.Can't find any really helpful howto's... wondering if anyone on here has done this?

I'm an experienced Linux developer who has run into a little problem. I'm using a National Instruments 8170 chassis, among the normal ports, it has a FDD and USB port but this model does not allow booting from a USB CDROM ( I tried a BIOS update, that didn't help either ). I made this cool customized 550MB FC8 LiveCD wtih X, GCC, various apps, etc. and a kernel 2.6.30 & 2.6.18 boot floppy disk with all the needed drivers. The floppy boots to a shell with all the busybox utils, etc. and detects the USB CDROM media and all its files.
My Question is: How do I get the kernel and initrd on the Live CD to start or boot after booting from the Floppy disk ?, I mean, I want to load linux again but this time from the CD after booting linux from floppy, if that makes sense. I'm just using the floppy to boot and recognize the USB CDROM. This can be done with MSDOS and loadlin but loadlin has an issue(it hangs) with the newer kernels (2.6.18 and greater). I searched for the loadlin source code to port it to linux but was unable to find it on the net.

I have successfully migrated my linux install to a new /, /home, /boot partition on my ssd. Everything works fine, except that it won't make the root directory on the right disk. When I change the root=uuid=<drive id> to my new drive everything is fine, but I can't automate that... in other words I have manually typed the uuid of my root-partition for about 100 times now and I am fed up with that how I can save the uuid of my new drive in the startup parameters?

My DVD drive has gone bad and with new Fedora 14 just launched I decided to install the same through the usb flash disk.
First I used dd: dd if=/home/prabhat/Download/Fedora-14-i386.iso of=/dev/sdb
It went on nicely and copied the iso nicely. But I could not boot with it.
Second time I tried livecd-tools: livecd-iso-to-disk /home/prabhat/Download/Fedora-14-i386.iso /dev/sdb1
It went on nicely, and finally declared something like - usb disk is not live .... But here again when I tried to boot it says MISSING OS. I checked the contents of the flash disk. It contained raw DVD iso image, one images directory, one syslinux directory. I checked the contents of the images directory, and I found it had the install.img. And yes, the /dev/sdb1 is bootable.

I want ot install a new opensuse 11.4 as yest another OS. Due to the fact that I already have 4 sda partitions, I have to make some changes. What I am thinking about is to copy the sda2 (windows recovery) data to some folder etc (nevermind), then delete the sda2. Then I want to create a new primary partition for the new suse 11.4 and install it. What is worying me is the grub boot menu. I was planning to edit the new one (the opensuse 11.4), with old data.
Code:
###Don't change this comment - YaST2 identifier: Original name: linux###
title Desktop -- openSUSE 11.2 - 2.6.31.5-0.1
root (hd0,3)
kernel /boot/vmlinuz-2.6.31.5-0.1-desktop root=/dev/disk/by-id/ata-Hitachi_HTS542525K9SA00_080105BB0F00WDHE41DC-part4 resume=/dev/disk/by-id/ata-Hitachi_HTS542525K9SA00_080105$
initrd /boot/initrd-2.6.31.5-0.1-desktop .....
Now my question is will the settings of (hda0,n), change due to the fact that I have deleted the sda2? I have a lot of unused space at the end of my disk and want to create a new "sda2" there.

This is the third 9.10 install to do this on two different laptops, so wondering what's up...
In both cases, the goal was to leave a large chunk of unpartitioned disk after the Ubuntu partitions, for a second OS install or a filesystem Ubuntu cannot create like NTFS.
When I install with manual partitions, the system can't boot and asks for me to insert a system disk and press any key. When I reinstall telling Ubuntu to "use the entire disk" it then works.
First laptop, first try:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
First laptop, second try without the /boot partition:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
"use entire disk" works perfectly.
Second laptop, first try:
Same thing, non-system disk or disk error, insert system disk.
Second try "use entire disk" is currently in progress but I expect the same to happen.

I had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.
I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).
These are the commands I used:
Quote:
p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*
[Code]....
I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...
So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.
It's still trying to use /dev/disk/by-uuid/412d... to boot.
What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

I have a netbook I'm not using and which I transformed into a server with Apache, Tomcat6, Netatalk, Webmin, BIND9 and Tor.
Problem is, the disks never stop spinning because all of the programs write a few kb at least every few seconds to disk, even when nobody is connected to it.
My question is: Is there a way to have the computer boot from disk like normal (maybe even a squashfs), keep ALL CHANGES to ram and then save to disk when either the ram is full (unlikely because the server is rebooted every few days) or at shutdown?
I thought about a mixture of ramfs and unionfs but I'm not good enough yet...

I am in the process of re-DL-ing the ISO as the checksums didn't match.
Mind you, that was with a shell extension in Win-Lose. Who knows.
Anyway:
I have the ISO (that I had previously) on a USB courtesy of UNetBootIn. All appears well until, quite quickly, I receive an error after the loading process which goes something like:
Code:
Error: cannot find disk at [hash-code - looks like 0ace5f etc etc, is about 12 char's in length.]Something very similar (but not same error I think) happened when I tried to do the same with my OpenSolaris or Fedora install. I.e., gets as far as the very beginning of the loader and then: bork.
At least one of them said "will reboot in 120 secs". Saves me the trouble!

I installed Debian on my PC with a Acer Stock motherboard (xc600) with amd64 and after the installation finished it told me to remove my installation media and reboot. After reboot I was returned this message ' ERROR: No boot disk has been detected or the disk has failed.'. I have verified with gparted using mint live OS that I have Debian installed on my system.
I got believes that this may have be caused by a broken grub or I need to configure something I don't know how in BIOS.
I will update the topic later..
My installation media was a USB 2.0 flashdrive with a Debian 8.2 Jessie Installer and 9 different Linux distros. I have installed Debian multiple times before on my laptop and never had this problem so I know how to go through the installation process and set the partitions.

I have xp/fc8 on an older ide drive and just installed a new sata 1T and planned to put fc10 on it but in the process I killed my fc8 installation. I told the installer that the other disks were off limits but it was somewhat confusing at the bootloader page. So, I suspect that I told it boot off the fc8 disk. If that is the case is there a way to restore the fc8 install by somehow rescuing the /boot partition on the fc8 disk?

It is a Sony E series, and it probably has to do with the fact that I'm a bonehead (or just better than the general populace) and installed Ubuntu along side Windows on the comp. Anyway, I now cannot boot into Windows at all. If I try to turn on the computer without my Windows recovery CD in the tray, it displays an error message: "Error: hd0,5 out of disk <grub> (or something to that effect)"
Well, it says something about grub. Now I'm desperate. I'm fairly computer literate, but I'm not some Linux superuser. All I have done on the Linux side of my computer is install update. What can I do about this? Preferably, I just want to get rid of Ubuntu as even though it is really nice and I do like it, I'd prefer my computer to just simply boot into Windows.
