is it possible that Ubuntu can affect my laptop booting from dvd. I used my external dvd drive to install ubuntu onto my ASUS N10JC, but now when i try to boot from the dvd drive it wont let me? I have boot device #1 set to dvd/cd rom and #2 set to Removable Device, everything else disabled. The drive boots on other computers including a Win7 and a gentoo. Could this be Ubuntu related or just something weird?
View 1 RepliesI installed Ubuntu on external USB hard drive and while booting I did got option to log into windows XP, Ubuntu. Both operating systems ran fine. i.e. GRUB had overwritten MBR and I was able to dual boot. Main issue: I have installed Ubuntu in external hard-drive so that I can use Linux whenever I want other people who are using same computer can operate on WindowsXP. Sometimes my external hard drive gives problem if there is loose connection and so that oper people using computer do not face any problem I want to disconnect external USB HD whenever I am not using Linux. GRUB menu was pointing to external hardrive so disconnecting it meant my system wont boot!!I rewrote MBR using WindowsXP CD recovery mode. Now I am unable to boot from external USB hard disk( I thought I would be able to if I choose USB hard drive in BIOS option but it did not work it logged into WindowsXP by default).Is there any way I can change WindowsXP boot.ini file so that it also shows Ubuntu in external hard disk? Or is there any way.(I do not want GRUB way as then I would have to keep my external drive connected to log into windows - which I do not want).

i'm trying to set up a triple boot for me newly bought iMac.
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.

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!
When my Western Digital MyBook is plugged into my desktop machine via usb everything works fine. The computer boots up normally to the dual boot screen, and all OS options will boot up normally. However, if I unplug the external hdd (whether that be when the computer is off, or I unmount it and then restart) before I get to the dual boot screen I get an error message informing me that I have incorrect boot media, and to insert and hit any key. Some background: I have checked the bios and it is set up to boot from the internal sata hdd as the first boot device, and there are no usb boot devices defined. Prior to making this a dual boot machine, it ran windows only, and had no issues booting when the external hdd was unplugged.
View 9 Replies View RelatedI need a hand with mounting an external hd on boot with ubuntu server. I am aware of modifying the fstab, but that doesn't seem to be working. Here is an output:
Code:
# /etc/fstab: static file system information.

# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name

The problem is with the last line. Once booted into the server, I can mount using the following command:
Code:
sudo mount -t ntfs-3g /dev/sdb1 /media/externalHD
I know I can work around it by running a script with the previous command at startup, however I think I am simply doing something wrong. Is there a better way?
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 boot Ubuntu10.10 from live cd and installed to my external hdd (thats Apacer AC601) . Installation completed but i cant boot from external hdd. i didn't create custom partition layout myself , I choose the option "use entire hdd". Everythings fine with Fedora core 14.
View 6 Replies View RelatedI 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 just installed Ubuntu 10.04 on an external hard disk. It boots very very slow. I get a black screen for about 2 minutes, with the led of the HDD regularly blinking. The hard disk is OK, so it's type isn't the issue here. Is there anything I can do about it?
I can't (don't want to) install it on my main hard disk, since I already have Ubuntu 11.04 and Windows 7 installed there and it's getting a bit too crowded.

View 5 Replies View RelatedI 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?
I was wondering wether it is possible to boot an eee 901 from an external usb cd drive? (for those who are unfamiliar with the eee, it has no internal cd drive) The cd drive is not listed in the bios boot menu.
View 2 Replies View RelatedI am dual booting windows and ubuntu. I bought a external hard drive to use as a backup solution. I like the idea of my external HD being an exact copy of my internal one so that if my internal one completely fails I can just plug my external one in and carry on (it's an internal drive in an enclosure).
I notice a lot of people use rsync to backup their home directory. Can I use rsync (or something else) to back up the whole drive including the Windows partition.
I installed Ubuntu to an external hard drive and I wanted it to be a portable OS I could take with me and still maintain my settings and files and what not. My problem now is, I cannot boot into Windows without having the USB drive connected. I also cannot boot directly to the drive by selecting the USB drive from my boot options on start up, I have to let it go into the boot menu.
So I need help with being able to boot directly from the USB drive on any computer, and being able to boot into Windows without having the USB drive plugged in. Hopefully this can be done without re-installing Windows.
I installed ubuntu 10.04 on external usb hdd after having the internal drive disconnected. When now I try to boot i can only do it from the internal. I can see the external when in ubuntu, but no booting. Also I can see the external in the internal grub menu but when booting disappears. I suspect that it has to do whith the designation of volume names, when installing from external the disk is named sda1 but in the internal grub is sdb1. How can I change the name to sdba1 in the external grub

From that time I wasn't able to use my computer until I discovered ubuntu and used it on my netbook. I, then, downloaded Windows 7 (lite) and got it on my netbook. The only problem that bugs me is that I want ubuntu and windows 7 and I cant because there is less disk space.

The thing is i want to have windows xp on my internal drive and ubuntu on the external. Not very hard but i want it so that i can choose what to boot when i start my computer and i also want to store other things then ubuntu on my external drive so i can use it in xp also
The reason i want ubuntu for is to use it while watching movies or chatting osv and use xp for games and my animation programs since they tend to be quite hard to get to work on ubuntu.
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?
