  • How to fix "Disk drive for /boot/efi is not ready or not present"?

    - by N.N.
    After I updated BIOS/UEFI version to 1101 on an Asus P8Z68-V PRO motherboard Ubuntu (11.10) did not boot. After POST all I saw was a black screen with a blinking cursor in the top left corner. I booted an Ubuntu 11.10 live-CD and set the flag for the 20 MB partition before my boot partition to "bios_grub". Then I was able to boot and login. But now every time I boot and Ubuntu loads I get the following message: Disk drive for /boot/efi is not ready or not present. Continue waiting or press s to skip or m for manual recovery. I am able to login if I choose to ignore it by pressing s, but what does this message mean? How can I fix what the message warns about? After logging in I have noticed that /boot/efi is empty. The following forum post speaks of the same issue ubuntuforums.org/showthread.php?t=1893030. Updating to the latest BIOS/UEFI - version 3203, did not have any effect on this issue.

  • Install GRUB to Ubuntu Partition

    - by Noel
    So my computer has the following partitions: /dev/sda -- (I know this isn't a real partition, but more so the boot loader) /dev/sda1 -- (Windows 7 Boot Loader) /dev/sda3 -- (Windows 7) /dev/sda4 -- (Data partition, NTFS) that means i have /dev/sda2 as free space. I do not want to change the MBR of the computer. I would like /dev/sda2 to contain GRUB AND Ubuntu. So ideally when I turn my computer on, BIOS would ask if I'd like to boot Windows 7 or Ubuntu(or Grub or partition 2), and I could choose either one. But I would like Grub and Ubuntu to be on the same partition, so they will not interfere in any way with windows or window's boot loader/partition (sda3) How can I do this? Catch: when formatting partitions, Ubuntu does not give me the option to make them virtual partitions, so that makes things harder. I tried: installing Ubuntu to /dev/sda2 (which I formatted as ext4) and then told the Ubuntu installer to install the bootloader to /dev/sda2. But when I select "Ubuntu" from BIOS's boot selection, it loads a black screen and says "invalid arch independent ELF magic grub rescue _" and allows me to input stuff. How can I fix this, or tell my computer where Grub is?

  • How can I make my PCI-E graphics card visible to Ubuntu when the motherboard has integrated graphics

    - by Norman Ramsey
    I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first: Integrated graphics PCI graphics PCI-Express graphics (PEG) I set the BIOS on PEG, but I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.) I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one. Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says Current usage: Unknown There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset! Other information: The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card. Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power. It gets all its power from the PCI-E slot; there is no external power connector. The BIOS is an AMI Award BIOS. My question: how can I make the PCI Express graphics card visible to Ubuntu?

  • Alienware Aurora R2 Slow Boot Up

    - by James R
    I have an Aurora R2 bought a few years ago, and recently I decided a RAM update and new Samsung SSD would be good for speed. So now it's super fast, with the exception of booting up. It still takes good 2 minutes to get past the first splash screen on the BIOS, it's only the BIOS, after that it's like lightning. I've Googled the issue, and the usual problem is the BIOS trying to boot from anything it can, with the fix being to change the boot menu. However I've changed it now, and it's still slow. When I disconnect the USB devices it speeds up, but I can't do that every time I want to boot the PC up! The only other option I can think of is upgrading the BIOS, however it seems that A04 is the recommended on for Aurora R2s, so I don't know if upgrading the BIOS could cause issues, especially not if it doesn't solve the issue. Also, when I disable my original hard drive in the boot menu, the PC won't boot up. Despite the Samsung one being fine to boot from, and the original not being needed as far as I know for starting Windows, it gives me an error message and makes me restart the PC, with a new boot configuration (with the original drive as second choice). Any ideas on how to make the BIOS boot faster? And why I need to have my original drive in the boot menu?

  • Why is my new PC so slow at startup?

    - by rumtscho
    Bought a new PC this weekend, and it works really good. Only I have one big problem: startup time. Its BIOS needs 62 sec to load, then from Grub start to pw entering screen it's another 26 sec. I think this is a lot, because my old PC needs 34 sec for BIOS and another 8 sec to pw screen. After I enter the pw, the desktop is usable with practically no delay on both. The new PC is a core i7-930, running a Lucid Lynx 64 bit from a Intel Postville SSD (no internal HDs). The old PC is a Pentium 4 celeron (forgot the clock speed) running a Lucid Lynx 32 bit from an ATA 100 hard drive. Neither PC is overclocked. The new one has boot sequence 1.DVD ROM, 2.SSD (connected over SATA in AHCI mode), 3. removable drive. The old one boots from 1. DVD ROM, 2. HDD, 3. Floppy. Neither has a second OS installed. The new one has less software installed than the old one (I think), but the boot time difference was noticeable even before I made any installs. As far as I know, just the SSD should be enough to make a noticeable difference in boot time. I thought that having a good mainboard on the new PC as opposed to the basic office model on the old one would also mean a faster loading BIOS. If these assumptions are right, I guess I must have misconfigured something in the BIOS of the new PC. How should I configure it for a fast boot? It has an ASUS P6X58D board with an AMI BIOS, if you need the BIOS revision number I could post that too.

  • Use external display from boot on Samsung laptop

    - by OhMrBigshot
    I have a Samsung RV511 laptop, and recently my screen broke. I connected an external screen and it works fine, but only after Windows starts. I want to be able to use the external screen right from boot, in order to set the BIOS to boot from DVD, and to then install a different OS and also format the hard drive. Right now I can only use the screen when Windows loads. What I've tried: I've tried opening up the laptop and disconnecting the display to make it only find the external and use the VGA as default -- didn't work. I've tried using the Fn+key combo in BIOS to connect external display - nothing I've been looking around for ways to change boot sequence without entering BIOS, but it doesn't look like it's possible. Possible solutions? A way to change boot sequence without entering BIOS? Someone with the same brand/similar model to help me blindly keystroke the correct arrows/F5/F6 buttons while in BIOS mode to change boot sequence? A way to force the external display to work from boot, through modifying the internal connections (I have no problem taking the laptop apart if needed, please no soldering though), through BIOS or program? Also, if I change boot sequence without accessing external screen, would the Ubuntu 12.1 installation sequence attempt to use the external screen or would I only be able to use it after Linux is installed and running? I'd really appreciate help, I can't afford to fix the screen for a few months from now, and I'd really like to make my computer come back to decent performance! Thanks in advance!

  • Windows 8 BIOS - Boot Ubuntu from External HDD

    - by F3AR3DLEGEND
    My laptop came pre-loaded with Windows 8 64-bit (only storage device is a 128 GB SSD). Since it is my school laptop/I've heard creating a Linux partition alongside Windows 8 is not very wise I installed Ubuntu onto my external hard drive. I have a 500GB external HDD with the following partitions: Main Partition - NFTS - ~400 GB Extension Partition / - ext2 - ~25gb /home - ext2 - ~30gb swap - ext2 - 10gb /boot - ? - 10gb ? = not sure of partition Using the PenDriveLinux installer, I created a LiveUSB version of Ubuntu 12.04 (LTS) on a 4GB USB drive. Using that, I installed Ubuntu onto the external hard-drive, without any errors (or at least none that I was notified of). Using the BIOS settings, I changed the OS-loading order so that it is in this order: My External USB HDD Windows Boot Loader Some other things Therefore, Ubuntu should load from my hard drive first, but it doesn't. Also, my hard drive is in working condition, and it turns on when BIOS starts (there is a light indicator). When I start my laptop, it goes directly to Windows 8 (I have the fast startup setting disabled as well). So, is there any way for me to set it up so that when my HDD is connected, it will automatically load Ubuntu? Thanks in advance!

  • after BIOS splash, will not boot -- asks me to select an OS, but it just reboots

    - by user92040
    I'm running Linux Mint 13 MATE 64-bit. Everything has been working for several weeks. Yesterday, when I tried to boot up my computer, after the BIOS screen flashes I reach a screen with a black background that reads at the top: GNU GRUB version1.99-21ubuntu3.4 Then there is a box in which I can select from the following lines: Linux Mint 13 MATE 64-bit, 3.2.0-31-generic (/dev/sdb2) Linux Mint 13 MATE 64-bit, 3.2.0-31-generic (/dev/sdb2) -- recovery mode Previous Linux versions Memory test (memtest86+) Memory test (memtest86+, serial console 115200) At the bottom it reads: Use the ? and ? keys to select which entry is highlighed. Press enter to boot the selected OS, 'e' to edit the commands before booting or 'c' for a command-line. I have no idea why it started doing this and, worse, I have no idea how to get out of here. No matter which option I select, I can't get it to boot the OS. If I select either of the first two, it reboots to splash the BIOS and then I'm right back where I started. If I choose "Previous Linux versions" I get essentially the same screen with only two choices (which are the same as the first two choices listed above, Linux 13 MATE and the recovery mode). Again, choosing either one of those results in a reboot. If I try to run either of the memtest options, it reads: error: unknown command 'linux16', Press any key to continue... Then it brings me back to the same screen Can anyone help me please? Intel Core i5-2500 ASUS P8Z68-V LX Intel Motherboard G.

  • Delete Ubuntu and Grub from PC (and BIOS unaccessible)

    - by Temitope
    I've really done a mess while upgrading 12.04 to 12.10, or my PC did, or ubuntu did, I can't really tell. The situation now is I have a dual booting machine, Windows 7 and ubuntu 12.10 -When turning on the PC, I can't access boot options, I've tried every thing, esc, f1 f8, f10 (I have a Hp pavilion) but all I can see is a short-lasting screen with three lines reading something like "error:files not found" or "link not found". So the PC turns to the Grub loader screen. This is already a BIG problem. It means I can't change boot order, and I'm diperate, since it doensn't seem that repairing my operating systems will bring my BIOS back. -If I chose Ubuntu in grup, it loades but then frezes on the desktop, I may be having problem with unity3d, or compiz, which was reported to be crashing the first times I started ubuntu. Now, after turning off and on the pc several times, no crash is reported again. Ubuntu just load my background image and nothing else. Not the side menu, not the header, nothing. Althogh the system seems "functioning", when I press the power button on the PC, for example, the normal shutdown dialog window appears. -If I chose Windows, Grubs tells me that something is not found, and to press any key to continue; I do it and then Windows loads perfectly. What I now want to do is 1- use EasyBSD to change boot order and boot Windows partition first 2- delete the ubuntu partitions from within windows disk manager What I except happening is that My PC turns to, or near to factory booting settings: I press the power button and Windows loads without asking me nothing I have acess to all my hardisk from withing windows Is that what will really happen? Are there danger I'm not seeing? What I don't except happening is The BIOS access key return functioning How could I eventually solve this? I would like to reinstall Ubuntu, 32 bit version this time.

  • How to Dual Boot Windows 7 x64 and Ubuntu 13.04 x64 as BIOS, not EFI

    - by Dizeke
    I want to dual boot windows 7 x64 and ubuntu 13.04 x64, but when I installed it, it doesn't boot. Only windows was booting. I installed ubuntu with " / " 50GB and a "swap" partition 4GB. Could it be that it doesn't work because I'm on bios mode, and that my disk is MBR, not GPT. My laptop doesn't have an option to change boot mode to UEFI so as much as possible, I'd stick to MBR :( Acer Aspire 4755G Intel i5-2450M 2.5Ghz-3.1Ghz Nvidia GeForce GT540M 2GB 4GB RAM DDR3

  • Ubuntu on Mac mini and refit

    - by Thomas
    I have successfully installed Ubuntu pangolin 64 bit on a mac mini 2011 5,3 ( server version ). I have used the Ubuntu iso which I then converted to .dmg and dd'ed into an usb stick. I didn't want to keep OS X installed so I deleted the current partition and reformatted the drive as ext4 for / + a small swap partition. Everything seems to work nicely, but I have now a question since I read lots of reviews/howto when you people installed rEfit on Mac OS X. Did you use rEfit to be able to have a dual boot or there are other advantages by doing that ( apart that you will be able to download updated firmware for your hardware in the future via Mac OS ) like BIOS emulation and the like ?

  • My ubuntu partition was deleted and I can't boot from either a DVD or USB

    - by ropudito
    It's my first time installing ubuntu. I have Windows 7 and 8 before in my laptop (Acer Aspire 4752z). After Ubuntu (12.04) installed in my laptop, the Windows boot loader didn't recognize my Ubuntu so I updated grub from a live USB. And after grub updated, Ubuntu was booting perfectly but my Windows wasn't listed in the grub menu. So I follow someone instruction to update grub again. And after reboot, the grub menu didn't show anymore. After searching about this problem on the net and trying to update grub again and again, I decided to delete the Ubuntu partition from live USB. And shortly after, I booted to Windows with Hiren boot and I used mbrfix. But i think it failed. Now i cant show my BIOS setup or boot from DVD or USB. After that, the only screen i can see after booting is: error: unknown filesystem grub rescue>

  • Can't boot from liveUSB when trying to install it alongside Windows 7

    - by ali
    I'm very noob at Linux and installing techniques. I want to install 12.04 from bootable usb flash alongside Windows 7 (also tried live CD but not working) but computer is not booting from USB flash or LIVE-CD and boots windows 7 (Acer Aspire 4750g) and of course I have set the BIOS priority in the right way. There is one important point to tell that I have installed Fedora 16 on my laptop successfully and now I have it on my system. When I was trying to install Fedora I got some error and searched about it and got this point that I should delete a .efi file and then installation went right. In this case , what should I do to solve the problem? (I also don't need my Fedora anymore).

  • Throttle and overheating on Dell XPS Studio 1645

    - by Ross
    I realise there is an older thread on the very subject but that seems to be pretty dead. I just got a Dell Studio XPS 1645 laptop and the fan noise and overheating is pretty ridiculous. This is actually a well known problem with the laptop that is apparently solved with the combination of a BIOS update and the purchase of their 130w charger. I plan on buying this charger as soon as possible, however I've noticed that since installing Ubuntu the fan noise has became more permanent and the overheating is quite a bit worse too. I've had to turn it off twice to let it cool down for an hour or so because it starts seriously affecting the performance. It makes watching things, listening to music or leaving the laptop on while I sleep a real pain. If anyone has some new information on this issue or could help out in anyway at all I'd be very grateful. Thanks.

  • Ubuntu 13.04 on UEFI system with Windows Boot Manager as the main loader

    - by Mehrdad
    On my old laptop (legacy BIOS, MBR disk), this was perfectly possible to get working: I turn on the computer and see the Windows Boot Manager I use EasyBCD (or BootPart, or something else) to add an option to the BCD menu which allows me to boot into GRUB, and then into Ubuntu I can't figure how to do this on my new laptop (UEFI, GPT disk), whether in UEFI or legacy mode. Currently I've installed (and even booted!) Ubuntu on my laptop, but only with the help of an external GRUB (on a USB flash drive). How can I add GRUB as an option in the Windows Boot Manager on a UEFI laptop? (No, I don't want to change my primary boot loader. So no, I don't want to overwrite the Windows boot loader with GRUB.)

  • Booting but not rebooting from external USB hard drive, what could be the problem?

    - by user8276
    I have a Dell Inspiron 6400 laptop with a dead internal hard drive controller. It boots perfectly from CD or USB. I therefore removed the internal hard drive and installed Ubuntu 10.10 Maverick onto an external USB hard drive. It boots and runs perfectly when doing a "cold start" of the PC. However, when I choose restart/reboot in the Ubuntu menu (e.g. after an update), I get this error message from the BIOS: "No bootable devices, strike f1 to retry boot, f2 for setup utility, press f5 to run onboard diagnostics". I can make the system boot again by pressing f2 or f5 and exiting the utility without having done anything. Or, I can simply power off the system and do a new "cold start". Does anyone know the likely reason for this problem and how to fix it. It is not a big issue but an annoyance that I would like to fix if possible.

    i am a long time user of Ubuntu and this is the first time a such thing happens to me. I usually upgrade from a version to an other, but this time i wish to do a clean install. I want to totally remove my 12.04 and do a clean install of 12.10, i created a live USB then i restarted my computer to boot from USB, i got the following error: Product is covered by one or more of the following patents: US5,434,872, US5,732,894, (and many more) Under that i see: PCIe GBE Family Controller Series v2.38 Media test failiure Exiting PXE ROM And then it reboots I've searched a lot for an answer, i guess the problem is with something in my bios, but i didn't find a fix. I would really appreciate a fix for my problem. My laptop is a Toshiba p775 dual boot ubuntu 12.04 and windows 7.

  • AHCI, Power Mode S3 and HPET 64bit - please help with these settings!

    - by thetattoo
    my problem is the that for a Hackintosh (unofficial PC running OS X) I needed to set AHCI, Power Mode S3 and HPET 64bit. Now, I want to install Ubuntu (when 12.04 comes out) and was wondering if these settings will be right to use for Ubuntu. I read that AHCI is how the hard disks are accessed, Power Mode S3 is how suspend works with the RAM but couldn't figure out if using HPET 64bit makes any difference than HPET 32bit. What I would like is an explanation of what these BIOS settings do and what is best for Ubuntu. Thank you very much

  • Is the motherboard the cause of these errors?

    - by ianfuture
    Motherboard is : ASUS A7N8X-E Deluxe, Rev1.01, On start up get: "cmos checksum error - defaults loaded" error BIOS is reset everytime and can't boot to Windows off HDD. POST report is ok once I tell it there is no Floppy drive attached and not to seek it. The boot sequence starts then just as get to load windows safe mode options whole PC shuts down. BIOS is reset to defaults again. I've checked the battery and jumpers. Tried a known working battery. Changed Graphics card, changed memory, changed HD to one without an OS. Disconnected DVD drive. PSU is known to be ok. IN BIOS CPU is recognised correctly and memory is also recognised ok. So is it likely to be a bad motherboard or corrupted BIOS or something else? Thanks :)

  • Installing Windows 7 from USB on a Thinkpad T61

    - by Halik
    I am trying to install Windows 7 Professional from USB 3.0 flashdrive, on a Thinkpad T61. The problem is, Thinkpads BIOS will not detect the flash drive as bootable medium, and won't allow to boot from it. What I did: Enabled USB BIOS Support in BIOS (it was on by default) In startup menu, added USB HDD to boot order (it has '-' sign in front of it) Created Windows 7 install media with UNetbootin, WinUSB (linux tool) dd and Grub4DOS. As you can tell, currently, I only have access to Linux machine to make the flashdrive. What happens: The T61 BIOS shows '-USB HDD' in boot order menu. The '-' sign suggests that the plugged flash drive is currently not bootable. The same flashdrive (with the same Windows image on it) is booting without any problems on a Dell D430 and Lenovo Y550. Also, Ubuntu 12.04 install USB created with Unetbootin shows as bootable ('+' sign in BIOS boot order menu) and boots from the F12 boot menu. Additional info thinkwiki.org says that some Thinkpad BIOSes do not use MBR on flashdrives. It suggests using Extended-IPL boot loader, but the provided links are broken and there seems to be no mirrors. Solution: http://superuser.com/a/430186/54970
