Ubuntu Installation :: Transfer Grub From Old External HDD To New One
Dec 26, 2010
I have a laptop with dual boot Windowz 7 64 bit and Ubuntu 10.04 LTS 64 bit using windows MBR and EasyBCD. I have no issues booting into either. I also have a 500 GB external HDD which has a NTFS partition for backup data and Linux root and swap partitions at the end. I have GRUB installed on the external HDD MBR and can boot into Ubuntu on the external HDD via bios options. I recently bought a larger external HDD 1TB. Now so far I have made same partitions as old external HDD namely NTFS for bakup followed by Linux root and swap partitions. Linux partitions were cloned using disk cloning while on NTFS partition I only copied data. How do I copy the GRUB from old external HDD to new one so that I can boot into my linux on the new external HDD? BTW the new HDD is Western Digital Passport Essential SE, which also has some factory installed image at the start of drive.

I am trying to install 10.04 to an external HD (not flash). I ran the live CD, installed to it and all seemed to work fine, but I don't want to use GRUB. I ran 7 repair and did a bootrec /fixmbr and it's booting normal, but I can't boot to USB.I want it to boot normal, unless I hit F12 to boot to removable device. Not much of a Linux person, but I am trying to be.

I'm using a Toshiba Tecra Laptop through a dock station with attached keyboard, mouse and display. I mainly use windows but also practice with ubuntu. After update to 11.04 I cannot select which system starts with the external keyboard and I must open the laptop and use its keyboard only for this task, once started everything works as usual.
As a partial solution I've tried to edit /boot/grub/menu.lst and force windows as default system. But on boot grub still shows Linux (the first line) as preferred system. Do you now what's wrong?
By the way, now I find a lot of files in /boot/grub. If I'm not wrong they weren't there with 10.10, do you know their purpose?

I have windows 7 64bit on an internal harddrive, a larger internal harddrive for storage and a 1tb mybook external for storage. I have an ubuntu 9.10 iso burned to a cd that i got from the ubuntu site and I had previously installed dual boot successfully on my other computer, a laptop.
I went to install it on my desktop as well and when i was selecting how much space to allocate i noticed it was using the mybook and not the internal. I couldn't see an option to change which harddrive it used so in my ignorance i allocated 50gigs to ubuntu on my 1tb external mybook. This was obviously the wrong decision as after restarting the grub bootloader would not open and grub rescue came up everytime after that.
I have tried booting from the cd, reinstalling from the cd, and using a windows 7 repair cd. I can't even get into non installed version of ubuntu to try and use terminal. I have spent the 5 hours on the internet trying to figure out what to do and i have no clue. I want to get ubuntu off the mybook and get back on windows 7 where i can then reinstall ubuntu properly on one of my internal harddrives.

The default (graphical) installer did not work on my PC (i7 quadcore 8 GB DDR3). I have installed Ubuntu using the alternative installer (Desktop, 64 bit) on my external USB drive. I installed grub on the MBR of the second drive (/dev/sdb) as I did not want to touch my (first) Windows disk. After reboot (chosing the USB drive as boot device, else Windows is booted) grub reports an error and enters the rescue mode. I tried all possible combinations of "root=(hdX,Y)" in grub.cfg to no avail.
I repeated the whole procedure but now disconnected the internal HD with Windows. Installation went smooth again (Windows disk was not seen this time), but after reboot (the internal drive connected or not) I again get (slightly different this time) grub error: can not find file.

I just bought a 1Tb hdd and reformatted to FAT32 it is connected via eSATA to SATA cable.At first I transfered music that initially was getting speeds over 100mb/s (according to nautilus) after about a minute it started to dwindle. Now most files will range somewhere between 8-20mb/s although I've only seen a couple go beyond.i edited hdparm.conf to enable DMAHere is the output of hdparm -Tt for both internal(sda) and external(sdb) hardrives.
Code:
/dev/sda:
Timing cached reads: 14872 MB in 2.00 seconds = 7444.68 MB/sec
Timing buffered disk reads: 372 MB in 3.00 seconds = 123.91 MB/sec[code]....
What is the issue this output leads me to believe that I should be getting the same speed I once got.I'm running Intel Core 2 duo at 3.00, ASUS P5Q (enabled AHCI) and 4gb ram 12gb linux swap. Also Karmic 9.10

I have Ubuntu/Vista dual boot desktop with Single HDD (200GB) that i cloned to an external USB HDD (320GB) using clonezilla. My intention is to use the external HDD as a backup to up running in case my 3 year old desktop HDD fails. To make sure the clone is good to use if need, i connected external HDD to USB port and tried boot from it but got "Error 18". I tried to Google got some infoDid a fdisk -lu and got the following.
Code:
Disk /dev/sda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders, total 390721968 sectors

I am running dual boot Ubuntu and windows 7 but have decided to ditch windows and go permanently with Ubuntu. How do I save my data files (email addresses etc.) to an external hard drive for downloading back on to my laptop when I have reformated it.

I've tried to be clever but as usual I didn't think before acting and missed a small detail.
I have recently installed karmic (dual booting with Vista) on my dell xps laptop. The install went fine, I'm very happy with my new OS.
I bought a new Seagate 500GB portable external HDD. I got a bit over-excited and installed karmic on the external drive. This worked fine and I got a lovely (but slow to appear) Grub2 menu showing my vista and both ubuntu options.
My problem is that now, when I unplug the external drive, Grub fails and I get a grub rescue> prompt. So I need the external drive to be plugged in if I want to boot.
It seems I have done something to the grub configuration. I have read around the subject but I am not confident about how best to proceed.
I understand there is an 'advanced' option in the installer which will allow me to choose where to install grub. Presumably I want it on the internal drive so that I can boot without the external one plugged in.
Am I right in thinking I can just pop in my install disk and redo the installation?
If I indicate I want to install Grub on the internal drive, which partition should I aim for?
Will I get a grub option for booting to the external drive?
Will I be able to plug the external drive into a different machine and boot from it?
I haven't done anything with the fresh install on the external drive so I don't mind losing that.

I have an hp laptop and i had ubuntu on it for 3 years. my hard drive started to fail a while ago (i had ubuntu 10 on it until 1 week ago) and a then it all went black...I took the laptop to a repair shop, they told me it was the disc, so i bought a new disc, installed it on my laptop and reinstalled the new ubuntu 11. so far so good. i have now a working OS, internet connection and i can in fact type this message.
The thing is: all my files are on the old drive, which doesn't load/boot/start/read anymore. I have tested it on some friends's pc, tried a few HD disgnostic tools, they all send the same message: "fail"
I then tried to mount my old drive (with all my precious files in it) on my laptop as an external drive (usb) hoping that ubuntu 11 could read it as an external usb key: it gets read by the system, but it shows no files at all. it also shows an error message saying the drive can not be mounted, with some "sdb1" thing. i am sorry but i'm really dumb when it comes to tech language.
Then i tried to boot it on start-up but i got the grub rescue> thing and nothing else, just a sad, blinking cursor to recover my files,i have also tried testdisk but couldn't understand very well how to use it, and then photorec, from which i recovered bits and pieces of files, with no name. some of them are just parts some of them are complete.
My problem is: i have to get access to my files, as I use them for work, i couldn't do a back-up recently and i have some real important deadline to meet... for which i need those files. is there any way i could solve the grub issue and have that drive load/mount again as external usb?

how to transfer large files from my laptop to external hard drive. Problem occurs when I'm sending Blu-ray films (4.4GB) to external, gets to 4GB and then comes up with error. Is there any way of breaking it up and then merging when it reaches the hard drive or is there a way of sending it as one whole file.

i recently started dual booting with Kubuntu using an external HDD. GRUB works fine, but it sees two Kubuntu's on the drive. In GRUB, i see "Ubuntu-Linux Kernel (for some reson its not identified as Kubuntu) on /dev/sdb1 (external drive)", then i see recovery mode beneath it, and the exact same line right below recovery mode, followed by another recovery mode. strangely, selecting either one boots into kubuntu no problem at all. is this a problem and is there anyway i can delete the duplicate entries?

Here is my current setup for my laptop: I dual boot Windows Vista and Ubuntu 9.04. Vista is on the laptop's HDD while Ubuntu is on an external USB HDD. When turning my laptop on, if the external hard drive is either not on or disconnected, I get "Error 21" and nothing happens. Normally this wouldn't be a problem, but when I need to take my laptop somewhere where I do not have access to my external HDD, it is rendered completely useless. So is it possible to set up GRUB (or possibly another bootloader) to boot regardless of whether or not it detects the drive Ubuntu is installed on?

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
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x8da4c52c

/dev/sda1, 1, 1355, 10877952, 27, Unknown.
/dev/sda2 *, , 1355, 38914, 301961224, 7, HPFS/NTFS. (The commands changed this from FAT32)
Disk /dev/sda: 8054 MB, 8054636032 bytes
8 heads, 32 sectors/track, 61451 cylinders
Units = cylinders of 256 * 512 = 131072 bytes

Disk /dev/sda: 250.1 GB, 250059350016 bytes

Device, Boot, Start, End, Blocks, Id, System.
/dev/sdc1, *, 1, 30402, 244197376, 83, Linux.
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.

Having a bit of a issue with Debian Squeeze and transferring files to the Sony PSP..Hook up PSP to USB port and Debian mounts it..I go to drag a 125 meg mp4 to video folder..Copy windows takes about 10 seconds to transfer it..Exit USB mode and there is no video there. Go back into USB mode and look at video folder on the PSP memory stick and there is no video..It vanished. From another after copy progress closed I right clicked PSP and unmounted it..
It error-ed saying device was busy and could not unmount..Looking at light on PSP i see memory stick is still being written to..i wait for light to stop flashing..About a minute or so..Then am able to unmount it..Go to PSP video and theres the video ready to be watched. Debian isnt accurately showing the copy progress...Its showing complete when it isnt..I have to watch the light on PSP to know when it is truly finished.

I have windows on my box, I have fedora 14 on my external that goes through my usb. Grub is installed on my usb. Since the only thing stored on my external was fedora i really didn't have to do much to it. just go into bios and boot from usb. Now that im using fedora more, Id like to add Vista to my choices. I guess the numbers change once your using an external drive. Ive read some of the problems like mine but they didn't quite do it. Im going to inclose 2 screen shots of my drives/partitions and my grub.conf.
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that

I recently decided to try out openSUSE 11.4 with gnome and install it on my external USB HDD. To do so i followed this guide here SDB:Installation on external hard drive - openSUSE
Unfortunately after finishing the install when trying to boot into the system i got GRUB error 17. The only thing i did differently from the guide was placing the /boot partition after a ~800 GB NTFS partition with my data.
I tried to solve the problem by reinstalling the system with different settings than before. After completing all of the steps in the guide mentioned i disabled booting from MBR and enabled booting from /boot partition. Also set the installer to write generic boot code to MBR.
Though after the installation i realized that grub is not loading at all this time and went on to fix it by completing the steps here SDB:All about GRUB - openSUSE . After doing so i'm back to GRUB error 17.

using Slackware 13.0, and whenever i trasfer my files to USB, like copy or cut and paste, it will show as if file transfered in an instant,like click paste and poof.the whole 1 gig file transferred in one second, and it wont show dialog box of transfer process, and then i have to predict some minutes and wait (till the transfer actually finishes, i have to usually see my USB's transfer indicator light), if i plug out before or my prediction goes wrong, i end up with corrupted files. This aint related to window manager, as same is case for KDE and XFCE tried thunar, konqueror, midnight commander, all of em resulted with same problem.

Alright I couldn't explain it in the title for this post so I'll try to do my best here. As of right now I'm dual booting windows xp and ubuntu 9.04. Windows is on the c drive and ubuntu is on my g drive. They are both on the same hdd just different partitions. I have another hdd that I would like to install 10.04 onto and transfer over all of my settings (and files if possible) from 9.04 to the new installation of 10.04 on the new drive. Afterwords I'd like to uninstall 9.04 from the g drive and have that part of the partition back to continue storing programs and other files for windows. Basically I want each operating system to have their own hdd but I would like to transfer my settings from 9.04 to 10.04
Is this possible? I don't have MUCH that I don't want to lose on my current ubuntu, my main issue was that it took forever to get the wireless internet router to work and it finally does and I don't want to have to go through that again. I also don't want to lose my sound system settings because that took FOREVER to get working properly, and honestly I don't remember how I did it now, it was so long ago.
So if this is possible a little guidance would be great. If it's not possible let me know, I'll just start over fresh and clean with a new beginning and tinker around until I get everything working again.

slow usb transfer speeds has been resolved in 11.04 (Natty Narwhal)? I am currently using Lucid and facing the problem of slow usb transfer speeds which has always been there in ubuntu but everything else is running just fine for me so I see no reason to upgrade yet unless the new OS has solved this problem.

i would like share what i did when i migrate my ThunderBird 3.1.7 including (extensions, calendar, settings, addressbook) windows 7 to ubuntu 10.04. 1. Archive(7zip) the mail database or the thunderbird folder in the windows 7 which is in the location (C:Users(Ur Username)AppDataRoaming) 2. Install the TB on your linux and open it to create the ****.default folder and the profile.ini in the home/.thunderbird/* Note: althought your windows thunderbird archive backup has the ****.default and profile.ini it doesn't work in my case when i replace or put it the the home/.thunderbird/* directory 3. When you open the TB in the first time it will create *****.default and profile.ini, dont replace or delete it as i said above, what you must do is copy all the files or content in the directory of ****.default in the windows 7 backup archive which is in location (/Thunderbird/Profiles/.default/*) to the home/.thunderbird/ all of it but first remove the content of your ******.dafault and now its almost finish 4. Start ur TB and its ok Note: In my case the lightning calendar doesn't sync to google i reinstall my lightning and provider of google extension before it work. I think this is the 5th time i migrate my TB mail from windows xp to 7 to linux..
