I just installed maverick netbook edition on an external hard drive, creating my own partition table. When I tried to boot the drive, grub rescue mode told me file not found. I installed again and used the default partition table and got the same error. I gave up and tried to boot my fedora 13 internal hdd but was told that there was no such device. I looked through these forums and ran a bootloader script and was told that my internal hdd had a bootloader but my external didn't. I tried to load the kernel through grub rescue, but the file system was unknown to grub. The files are still on my internal drive and I don't want to reinstall just to boot it.

I cant boot from my External HD with ubuntu installed.
I get this message:
error: file not found. grub rescue>
In an attempt to fix this problem, I tried using the following sudo command:
sudo mount /dev/sda5 /mnt
sda5 does not exist, I tried 4, then 3, then 2, and it worked, but that was a partition of my internal HD containing windows 7.
I also typed in:
sudo grub-install --root directory=/mnt /dev/sda
not I get the following error when I try to boot from my internal HD:
error: no such device: 57288a24-5d12-4fb1-b27e-eb09a1f9b7c6. grub rescue>
Is there a way to get grub to boot into windows 7 again?
When I type:
sudo fdisk -l
I receive a list of my drives and their partitions, This is my assumption as to what drive is
Which:
/dev/sda1 = Vista loader, for Windows 7
/dev/sda2 = Windows 7 (At least I hope its still there.)
/dev/sdb1 = Bootable Flash Drive.
/dev/sdc1 = External HD.
The text from the terminal is as follows:
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Eventually I would like to fix the error I get when I boot from the external, I would like to to boot to ubuntu, but for now I am concerned with getting my internal HD to boot windows 7. Where I originally found the terminal commands to begin with. I think sda5 is where linux was installed in the example I found, and didn't realize it.

I have an HP Pavilion that was/still is running Vista. I recently decided to dual-boot to Ubuntu from an external hard drive. Both systems will boot up fine its just that for some reason it won't boot to the internal drive (with vista) unless the external is connected. I just put the HD in another laptop only to have the same problem.

I was having a hard time installing Xubuntu on a an old Japanese FMV Biblo LOOX S73A, with no internal drive. trying both from a USB stick and from a CD ( I think the USB's were USB 1's, not sure) but it was finally rolling with the CD---the bios lists USB booting- yet things happen, power shortage and the battery was out-
I'm stuck with a broken Xubuntu intall I have 3 grub options, regular, recovery mode and mem test I've tried to reinstall forcing the computer to boot from the CD in the bios, but get "no os found" If I let it boot from the hard drive, I get to Busybox/initramfs commands that I know nothing of. I just want to do a clean reinstall of the whle thing, but cannot find out how to do so. as mentioned this bios has an option to boot from USB CD ROM DRIVE, hard disk, or floppy
[Code]...

I have an older laptop with a broken CD drive so I cannot boot the CD Drive with my ubuntu image. The laptop does not support booting from a USB drive either.So what I did was take the HD out of the laptop and using a USB enclosure plugged it in to my Win7 desktop. Then I booted from my Ubuntu CD and had Ubuntu install on the USB Drive. Took the USB drive off, and put it back in the laptop. It seems to work except it looks like it was installed with my desktop hardware. Also, every time it boots it starts at a recovery screen asking if for several boot options (including win7 which does not exist on the laptop!).

Out of curiosity and stupidity, I configured 2 extended partitions to LVM in gparted. Now, I can't boot into X window, and there's only GRUB command line during boot.

I have an external hard drive connected to my iMac. I have installed Ubuntu on unallocated space on my external, the first time I chose to put the bootloader on the external but when I booted up the computer and held the Option key it didn't recognize an OS to boot from.I am currently reinstalling Ubuntu but placing the bootloader on the internal hard drive hoping that the Mac boot menu will recognize an OS to boot from.

I'm having an issue installing Fedora 11 on my system. After the install, I remove the DVD media, reboot the system, and it reports an error stating that Windows cannot start, missing or corrupted hal.dll file. I appologize if this is a common problem or has already been answered. My searches haven't yielded helpful information, mostly what I've found is people attempting to setup dual-boot machines or boot Fedora via the Windows Boot Loader.I have experience in computers, although I am completely new to Linux/Fedora. Through my work, I have experience using AIX, but no experience installing or managing drive partitions.The system in question is a 5 year old Windows XP system that I built myself. The system has two drives (C: and D: in Windows). The C: drive was the Windows install drive and the D: drive was added later for additional storage. I am attempting to completely overwrite Windows on this machine. I want it to single boot into Fedora 11, I am not looking for a dual-boot system. The system will become a network file server.
The specs of the system are...
Processor: AMD Athlon 64 3500+
Mobo: Gigabyte GA-K8NSNXP-939
RAM: 2GB
I downloaded the DVD iso for Fedora 11 x86_64 via Bit Torrent, burned the ISO to DVD and booted the system from DVD. I ran through the install (Anaconda 11.5.0.59) and see the following information on the screens..

I have sevral older machines that cannot boot from usb. Until now I have installed fedora using the provided boot.iso on a CD and an external USB dvd drive with the full install DVD.
With Fedora 11, this fails. It gets as far as "finding storage devices" and fails, telling me that an unhandled exception has occured. It offers to save the details, but freezes looking for a suitable location. I have no such problems with the same DVD/external rw drive on systems that can boot directly from usb.

I have an Acer netbook that I installed Remix on. Now I can't get the thing to boot from the CD drive which is connected via the USB port. Any suggestions? I set the boot order with the CD drive first and the HD last.

I have installed "open-SUSE 11.4" on a "500GB Free Agent External Hard Drive". I didn't have any problem in booting since last week that I booted it from my laptop. Also I did it before several times from then when I try to boot it e.g. from an "Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz" PC the time between loading INITRD and starting boot sequence messages lasts nearly 30 minutes!(i didn't actually measure it but it take a long time in the same order). after starting boot sequence which is showed on monitor everything looks normal. e.g copy of files would be done by speeds between 2MB/s to 30 MB/s depending on the targets.I used to use the external hard derive to boot from different laptops and PC's from start but I didn't have such a problem anytime.

I want to properly install Unbuntu on my multi boot pc. I would like to install to E partition which is currently ntfs. I have never installed Linux. What drive should the boot loader go? I can format E partition during install? Does it still need a swap file partition? If so, can that be made from E partition? How big? I'd like to have a boot menu to choose Ubuntu or a choice that takes me to the windows boot loader. Would that boot loader get wiped if I did a fresh install of 7 to the I drive? Also, what would be the proper way to upgrade Ubuntu? I see a lot of post where people are doing it wrong.
Here is my drives layout. Should install Ubuntu to my SSD J drive instead? I tried the live CD. Seems to work well. I have a Asus Max Formula MB, Phenom II 6core, ATI 4870. MB has a built in Via sound card. Not sure if that was working.

installing Ubuntu 10.04 on my notebook. Currently, I am using IBM Thinkpad X31 with docking that has swappable 2nd HD. The 1st internal HD has WIN XP on it. I had successfully installed Ubuntu 10.04 on the 2nd HD and everything work properly with GRUB menu asking which OS to boot when start the computer. However, when I have to swap 2nd HD out with DVD-Drive or undock, it won't allow me to boot into Windows XP -> showing device is not found and prompt to "Grub Rescue" command. It will only boot if I retain 2nd HD in the dock. So I will like to know how to make Window XP boot without 2nd HD, and still able to get in Ubuntu when I insert 2nd HD into the dock?

I would like to triple boot vista, opensuse and ubuntu.
I need to set aside 165 gb for Vista (which has been backed up to an external drive).
Would like to make a fresh install of Ububtu and Opensuse with Ubunto being the main OS. I figured 100 GB for Ubuntu and 55 GB for Opensuse would probably be fine (the remainder I need to set aside for Vista).
Ive popped in the Ubuntu DVD and am about to install it but am stuck on the "allocate drive space" part. I do not understand how to partition the hd and what to set each partition to in the "Use as" and "Mount Point"

After removing the Windows HDD from my laptop I installed Ubuntu to a new HDD that I installed in it - it works fine when used as an internal drive. But now I have put the Ubuntu disk in an external enclosure and replaced the original Windows HDD internally.
Now, if I change the BIOS boot priority to CD/DVD -> USB HDD -> Internal HDD will it be the case that I can boot Ubuntu when the external HDD is connected and Windows when not?
Also, if I boot to Unbuntu from the external HDD, will the internal Windows drive be left untouched? I'll be in pretty hot water at home if I damage that!

I Installed Ubuntu 10.10 on an external USB Disk Drive - I had chosen to install the boot loader on this drive. When I tried to boot from this drive, I get the the following message:
error: unknown filesystem
after that I get "grub rescue>" prompt
The install was done on /dev/sdb2
I have also tried update-grub using ubuntu 10.04 that i have on my internal drive. It did recognize that I had a kernel on the external drive but still no luck booting. This time i get.
error: no such device d4a3cb16-37b6-416c-a3bc-4f8d03318e28
error: unknown file system
error: you need to load the kernel first
Note that the long device name is the same as the mount point when i do a "df"

I have been trying for many days now to get ubuntu installed on western digital passport 1 TB USB external hd attached to my MacBook Pro (with intel Duo Core processor). I have installed the latest ubuntu 11.0.4 64-bit (needs to be 64-bit for work) on the external USB hd, and when I reboot rEFIt shows a new penguin icon. So, I selected that, and I see a screen with a penguin in the middle for a while, but then the screen turns black and just has a text error message that says "No bootable device -- insert boot disk and press any key". BTW, I checked that my Duo Core is definitely 64-bit. Also, ubuntu does run off the install CD. Even the wireless works and I can use firefox.
I have been reading lots of forums trying to find a solution. A couple that I have tried: 1) reboot and when in rEFIt, choose the sync option and resync the drives. I did that and now the penguin icon just launches a black screen with a different message about "no valid operating system" or something like that. 2) Another site said the key was to change where boot loader got installed, so during the installation, at some point near the end, there would be an "Advanced" button to click on, and in there I could set grub to install onto sdb, the location/name of my external USB hd. However, in the present version 11.0.4, there is no "Advanced" button on any of the install screens.
I really wish Mac just used a BIOS instead of this frustrating EFI. Do I need to edit or alter something somewhere? If so, exactly what?

I have a laptop that came with no OS. It has no internal HDD, so I formatted a 320gb external HDD and installed openSUSE 11.3 from another computer onto the external hdd. I can't seem to boot from the external hdd on the laptop though. I have it set as the primary boot source in BIOS. Is it possible to boot from external hdd or am I missing a step?

I am trying to install Ubuntu on a machine that already has Windows 7 on one partition. Obviously I intend to install it on the other free partition. So I downloaded the iso burnt it onto the disk and pop in the disk and the boot the machine. The installation screen comes up I selected the first option (Try Ubuntu without installation), I just see a prompt after a few seconds and then the screen goes blank and nothing happens. Unable to detect a signal, The monitor goes into standby. The same thing happens if I use "install Ubuntu" option as well. I downloaded minimal install version Ubuntu and tried to install with that. since its old school installation, the installation completed without any errors, but when I restart the grub come up and when I select to boot into Ubuntu, I see the same behavior i.e. the screen goes blank and never boots to anything. This is a machine on which I was using 10.4 until yesterday.

I installed OSS11.4 clean install over 11.3, it is suppose to be dual boot together with with winxp.
When i select to boot xp machine starts to boot but it boots forever and eventually
nothing happens further (HHD does not spin). Can it be grub problem or it's
winxp boot problem? When the actuall job of grub stops?
Boot loader location:
Bot form MBR, Boot from root partrition, boot from extended partrition.

I just recently installed ubuntu. I had always used windows before, and I wanted to try something different. My laptop's internal HDD is pretty full so I decided to install ubuntu on my 500gb external HDD. It is connected via USB A to USB B. So I run through the installation no problems at all. I partitioned 200gb of the external HDD for ubuntu. After install I could run ubuntu just fine and I really like it.
However now it boots through GRUB. I am not really sure what GRUB is but it says GRUB loading every time I boot up and then lets me choose what os to boot, but if I do not have my external HDD plugged in then GRUB fails to start and I cannot boot at all from my laptop. Is there a way that I can get it to boot windows from the internal HDD without having the external HDD?
