Ubuntu :: Boot Selection Failed - Required Device Inaccessible
Jun 20, 2010
I have a Ubuntu - windows 7 dual boot (in two partitions of the same HDD) desktop PC for a few months. I was learning terminal commands and, although I don't think I made such a big mistake, but the fact is that the a very strange thing happenned: "Preferences" and "Administration" from System disappeared as it did also "Applications". After rebooting the same it remained the same. No big deal, I thought, because I haven't yet saved any important work on Ubuntu. So I reinstalled Ubuntu. Done that everything was nice until I booted Windows... Since then I counldn't start windows after GRUB due to:
Status: 0xc000000f
Info: The boot selection failed because a required device is inaccessible."
Windows Live DVD Repair is useless. I've tried CHKDSK utilities, no result. Windows partition in Ubuntu's Disk Utility is OK but I can't access the files (all "broken links"), just can explore a few directories after which I find myself entering the same folder endlessly. I wanted to repair windows boot or at least recover some important files in Documents and I thought I had backup (but turns out that, for some reason that I'm still trying to understand, they aren't...).

I have 2 Debian OS's and wanted to put Fedora next to it.
Install went ok, but after rebooting it says: "No root device found. Boot has failed, sleeping forever."
During install from the live CD I didn't "v" the boot (efi or something?) because I thought Grub would take care of everything.
Should I just reinstall again and choose the Fedora bootloader? Won't it mess up Grub?

Reboot and select proper boot device or insert boot media in selected boot device and press a key. I got this error after: Reducing my Windows 7 partition by about 100gb. Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted. I now had two partitions a new 100gb Ubuntu partition and a 600gb (or so) Windows 7 partition.
All of this was done using a bootable USB with Ubuntu 10.10 and GParted partition editor. Now when I boot I get the "Reboot and select proper boot device or insert boot media in selected boot device and press a key." error.

How can I change the behavior of the selection buffer or a program that uses it ( I have xclip) to not send me text until the mouse button is released while clicking and dragging? This causes havok in the software I'm developing that tries to make use of the selection buffer. I need the full selection, not bits more bits more bits and then the full selection.EDIT: I cannot listen for mouse events such as button release outside of the GUI of my program.

I've read hundreds of threads on this problem but they seem to be intermittent and the resolution has been using a different kernel version.
I'm using the latest kernel but I still have this problem
Running Logical Volume Manager gui and attempting to extend the volume results in the same error.

I have a problem with vsftpd (latest version available, 2.1.0pre3) SSL. I've configured it to a nonstandard port, 65440, disabled connect_from_port_20 and run it as a normal user, from home directory. I can't use the SSL feature, every time I connect, it only reaches the login process. After logging in, I get the following error (when data transfer would start for LIST command):

Everything was going great earlier today when suddenly, my PC on a fresh boot, gave me a message that said something like "Ubuntu is running on low graphics mode ..". It was running a low res, i think it was 640x480, and gave me some repair options like a. Boot in low res mode for just one session b. Trouble shoot this error etc..There were 3 more options but i don't remember what they were.
i chose "boot in low res just for this one session", but it gave me the same error the next boot. Then i tried troubleshooting, which didn't work (restoring to a backup config was no use). Then finally i rebooted and started Ubuntu in Recovery mode, and i did something like "Fix broken packages" because , from the list of options it seemed like the only one which would help at that time.
But now, whenever i choose the Ubuntu option after starting my PC, it just restarts my computer. My other OS is Windows 7 which boots just fine. Hope someone can help me with this . In the meanwhile i'll try making a new MBR or something.

I have been trying for a couple days now to install 10.04 on a 250G hard drive that was a USB boot with 9.1. I want the hard drive in the case. The bios has been changed and does see the new drive. Boot selection has been changed to CD Rom. Everything starts out fine until step 4 of the install, Prepare partitions. There is no hard drive available on this step. The HDD is not seen by the disk utility either.

I locked the screen, came back, typed the password, screen remained black, though cursor was visible and moving. Nothing I could do to rejuvenate the screen. Had to switch to tty6, sudo shutdown -r now. Then, on reboot obtained kernel selection, it proceeded to displaying kernel messages, but froze on sdb, after 3 secs. I figured it was the usb, so turned off, removed usb cables to external hard drives, but again it froze saying something about firewire mouse, the mouse is also usb. I tried several times, but no matter what kernel I chose, I couldn't get it to boot. So I loaded puppy live cd, but now it can't access some parts of the disk. I was running utorrent and the folder with partially downloaded files can be accessed but there's nothing there (there was), and some folders can't be accessed at all.

I have several RHEL 5.0 servers in a secure network. We have identified around 200 rpms from 5.4 that we would like to upgrade. These servers have no connection to the internet, and very limited connection to the corporate network.
The application guys will not approve a full 5.4 upgrade as the app is reliant on certain rpms from 5.0.
So how can I create a boot disk that will install just the selected 200 rpm's. I have been trying to modify (remove rpms) from the downloaded 5.4 dvd, but with no luck. I have also had a look at anaconda, but seem to be going round in circles.

Ubuntu 10.04 I am dual-booting along with Windows. I need to change the order of boot options so that Windows is the automatic selection rather than Ubuntu. I cannot find the file to make the change and not sure what changes I should make when I do find it .

I've built several computers and installed Ubuntu on each one, and I've never had problems until my latest build. Here are the problems:The computer requires acpi=off to boot, and it won't boot with acpi=ht. I've searched for this, and there's a widely reproduced acpi troubleshooting guide that says that this means that there's something wrong with the acpi tables themselves, but I haven't found any fixes.If I go ahead and use acpi=off, then the computer works fine, but it hangs on shutdown. I've searched for this too, and the consensus seems to be to remove acpi=off from the boot options. This, of course, is not an option for me.

I'm running Lucid with the 2.6.32-28-generic and 2.6.31-11-rt(abogani's ppa) kernels, on a fairly new laptop.When I boot the rt-kernel, right after grub I get a message:Code:mount: mounting none on /dev failed: no such deviceW: devtmpfs not available, falling back to tmpfs for /devThen after a few seconds, I see a lot of fast moving text and then Ubuntu starts just fine.when booting the generic kernel, I don't see any text at all, but it uses just as long time as the rt-kernel, so I guess the problem affects both.

I've installed Ubuntu Server and set it up 3 weeks ago, it was working fine until today. Just recently, someone IM'd me @ jabber saying that none of services running on it work (http, ftp, svn, jabber, ssh). So I've checked stuff on my PC, and everything seemed to work well (at least for me). I've tried to see if http works via proxy, but it seemed like no. I've called my ISP, on their side everything looks fine, server was accessible via their machines too (well it's obvious). I asked them to see if other networks (TP, GTS Energis, Energis) could connect to it as well, the answer was - no. (I don't think it's firewall, since I didn't even had time to set it up...)

I get the error: Sorry, could not display all the contents of "trash": Operation not supported.Of course I know I can remove all the contents of the trash directly via ~/.local/share/Trash/ however, I'd rather have Ubuntu the work the way it was intended.I've tried opening Nautilus using the gksu command, but the problem persists.As per another post, I also tried a fsck on the partition, and no errors were returned.

I joined this forum today and I'm a fresher in Linux.
I have Fedora core 1 installed along with Windows XP in my desktop.
After starting the desktop the boot menu shows three items as follows:
Please tell me the difference between FEDORA CORE(2.4.22-1.2115.nptlsmp) and FEDORA CORE-Up(2.4.22-1.2115.nptl).
Also tell me which one should I use normally.

I'm trying to install ubuntu 9.10, downloaded the iso from the site and burned it on a CD, but when I boot from my cdroom drive and choose install ubuntu option I get an ubuntu grey logo for a couple seconds and the I get this error:
I tried downloading a new copy and burning a new CD but still have the same error, no matter what option I choose when booting the CD.
Does anyone now whats the problem? What I'd like to do is install linux as the only OS (formating everything else) not dual boot or anything, I'm new to linux so it'd help if you guys could give me details on how to fix it
I have installed previous versions of ubuntu on this same computer but using the wizard inside windows.
