  • How To Boot with "mem=1024m" Argument using GRUB - Ubuntu 10.04

    - by nicorellius
    I am still working on this question. This new one is a different question so I thought it would be good to post a new question. Is this the proper protocol or should I have just edited the other question? I'm running Ubuntu 10.04 with the kernel 2.6.32-22-generic on a Toshiba Satellite laptop. When I enter the GRUB menu (I have Ubuntu 9.10 installed as well), I can choose which kernel to boot. I use scroll down to the one I want and press "e" and I expect to be able to enter mem=1024m and force the kernel to use this much memory. But when I run cat /proc/meminfo or look in the process manager after booting wth this argument I still see all the RAM: ~2 GB. Am I using this boot argument incorrectly? The boot configuration (before I add anything) looks like this: insmod ext2 set root=(hd0,1) search --no-floppy --fs-uuid --set 10270f21-1c42-494b-bd3f-813c23f6d\ 518 linux /boot/vmlinuz-2.6.32-22-generic root=UUID=10270f21-1c42-494b-b\ d3f-813c23f6d518 ro quiet splash initrd /boot/initrd.img-2.6.32-22-generic The way I did this was that I added the mem=1024m after the last line and pressed Ctrl+x (Emacs save and boot the kernel) and the system booted. I tried adding mem=1024m to the end and the beginning of this list and it appeared to not change the RAM allocation.

  • Windows 8 changes GRUB2 in every boot!

    - by yxd
    I've installed Win8 and Ubuntu 12.10 both UEFI style (win8 first then ubuntu). GRUB2 shows me Both Ubuntu and Win8 entries. If I boot into Ubuntu is fine. I could reboot anytime I will see GRUB2 unchanged. The story changes when I Boot into Win8. When I boot to Win8 using GRUB2 it takes me to the Windows Boot manager (which only has the Windows 8 entry). I hit Windows and it boots fine. When I reboot, there's no GRUB2 nor Win loader. It has no boot loader. I boot a liveCD and download boot-repair and everything is back. It's a never ending cycle. Is GRUB2 supposed to load the Win boot loader? What can I do to fix it?

  • HP ProBook 4720s UEFI boot only manually into 12.04

    - by HainjeDAF
    I'm trying to get UEFI boot on my ProBook 4720s. Because I swapped the HDD for a SSD I had a blank canvas to start. The 12.04 Live DVD refuses to boot into UEFI, as do Alternate and desktop CD's. However, when I make a 16Gb flashdrive into a live FS using the bootdisk tool in ubuntu, I can boot from USB, manually into UEFI mode. It even sidesteps to DVD as medium when I boot from USB with 12.04 Live DVD present. I installed a GPT partitiontable with part 1, label EFI, fs FAT32, flag BOOT, mounts at /boot/efi part 2, label Linux-ROOT, fs ext4, no flags, mounts at / part 3, label Linux-SWAP, fs swap, no flags, mounts as swap So far, My system refuses to boot from harddrive by itself. I have to select "Boot from EFI file" and manually browse to (HD0,GPT1)\EFI\ubuntu\grubx64.efi any other option ends in "no system disk, please insert boot disk" I tried installing BURG, but that merely enforces non-efi boot. I tried most of the solutions I could find, but one says \EFI\grub\grub.cfg next says \EFI\ubuntu\ubuntu,cfg I'm confused and getting frustrated. How do I correctly install Ubuntu 12.04 in UEFI mode on this machine???

  • Must go through Windows Boot Loader to get to Grub

    - by Zach
    I just installed a fresh copy of Precise alongside Windows 7. I have to separate 750GB hard drives; /dev/sda holds the Windows partitions and /dev/sdb holds the Ubuntu partitions. Other than that, these are fresh installs of both Windows 7 and Ubuntu 12.04. Whenever I boot, Grub doesn't load, instead it goes to a black screen with a single blinking (horizontal bar) cursor in the top right corner. However, if I boot, hit escape right as the BIOS/POST screen finishes up, see the Windows Boot Loader and hit escape to make it go back to the BIOS screen. After the BIOS screen, grub shows up and everything functions normally; I can boot into Ubuntu or Win7. I don't want to have to do the Escape, Escape, Wait, Boot trick every time. I have no idea what would be wrong or what information I could give you guys to help diagnose. I have run a sudo update-grub and it found everything normally. I tried adding nomodeset flag in the /etc/default/grub line GRUB_CMDLINE_LINUX_DEFAULT which searching around made me think might work. Thoughts on what I could do to fix this? EDIT: I've tried changing the boot order so that both drives in the BIOS (both are labeled as "Internal HDD") have had a try booting first. I think the problem may be that every time I boot, the BIOS boot order is different... and I have to reset it. It seems to not be stable... but I'm not sure how to go about fixing that either. The machine has both traditional BIOS and UEFI. It came standard in "Legacy" mode; so it is currently set to boot through Legacy mode. I've reinstalled Ubuntu now, and now if I hit escape at the end of the BIOS/POST startup screen, it takes me to GRUB menu. Otherwise it automatically loads Windows. It seems like GRUB is now the acting bootloader, it just doesn't automatically start that unless I ask it to open a bootloader. In my other machines, it has always automatically started at the end of BIOS/POST. EDIT2: Using gparted, I just looked at my partitions, it would seem that my linux-swap partition is currently flagged as the boot partition for my Ubuntu install. I currently only have 2 partitions: one of "ext4" with a mount point of "/" and flag " "; and the "linux-swap" with mount point " " and flag "boot." If I change the boot flag to be on "/," it does not reliably solve the problem. After 10 boots: 2 Booted successfully to GRUB 5 Booted directly to Windows 7 3 booted to the black screen with the cursor and hung there Further research makes me think this is an issue of the BIOS not reliably booting hard drives in the same order or not finding both hard drives. If I ask it to create a "boot menu" sometimes it has 2 entries for "Internal HDD," sometimes 1. Also the list it creates changes order every time I bring it up; so it is not following a consistent boot sequence. Will report back if this is not an issue with GRUB.

  • 12.04 cannot boot from USB

    - by GhostRider
    The HP Pavilion g6 notebook is unable to boot from bootable USB stick created with Linux Live USB Creator. I was able to boot other systems using the same pendrive. I have changed the boot priority using F10. When I restarted, it didn't ask for any message like Press any key to boot from When I press F19, and selected the pendrive from the available options to boot from, while restarting it gives me a message: error while trying to boot selected boot image Though I looked into the possible suggestions here, none of them worked. Looking for any help? EDIT: I was able to fix the first issue, i'e ubuntu could be installed as secure boot option in the bios was not allowing the pendrive or cd/dvd to be detected. Now once i have successfully installed ubuntu 12.04, after the restart i was unable to find it in the os menu for selection and windows8 loaded by default Ubuntu version: 12.04

  • Boot to remote desktop

    - by mike737
    I'm trying to find out what existing options there are out there to boot a machine into a remote desktop (RDP). Ideally the user would have a USB key and just plug it into the machine and boot via it establishing an RDP connection to their virtualised enviroment (stored on a server). Essentially the anticipated flow will be Power On - Boot sequence - Remote Desktop Login screen.

  • Creating Windows partition in Boot Camp without an install disc

    - by Arvin
    I have an old Macbook1,1 which has Snow Leopard on it. I'd like to get Win 7 on it by using Boot Camp Assistant, however my superdrive is not working (It just spits out any disc I put in within 10 seconds). I know how to get Win 7 installed by using USB drive, but I still need Boot Camp to create the Windows partition for me. I've made an ISO file of the install disc which I've mounted, but Boot Camp won't pick it up. It seems to only look in the superdrive. How can I get Boot Camp to skip requirement of an install disc? edit: nevermind, as it turns out the partition was already created by the time it asked for the disc!

  • Unable to start GRUB2 on Triple boot Macbook Pro with OS X Lion, Windows 7 and Ubuntu

    - by Shravan
    I installed Windows 7 using Bootcamp. Then I created a partition from the empty space in the Windows partition and another 4GB partition for the linux swap using GParted. I installed Ubuntu 12.04 LTS in the the newly created partition from the Windows partition. Now GRUB2 does not load and I can only see the blinking cursor on the top right when selecting "Windows HD" from the 'option' key at the start up. OS X works fine but nothing else. Could someone please help me fix this? I am attaching the boot-info from the boot-repair tool. http://paste.ubuntu.com/1040169/

  • Can't boot after Deleted System Reserved Partition

    - by mauris
    I accidentally deleted the System Reserved Partition and now I can no longer boot into Windows 7. The installation of Windows and all my files still exists in the partition, but without the System Reserved Partition I can no longer boot. After I deleted the System Reserved Partition I moved left the primary partition to fill the space. Is there any way I can "reinstall" that System Reserved Partition and the boot files? PS: I only have Windows 7 installed. No dual-boot nothing.

  • How do I skip the Grub menu on a dual-boot system?

    - by Hailwood
    I have Ubuntu and Windows 7 installed and dual booting via Grub2. 99/100 times I will boot into Ubuntu. I want to speed up my time for booting into Ubuntu and really the Grub2 prompt is the part that adds the most time. So, I want to disable the prompt. I would prefer to be able to set it up so I can hold shift or similar at boot if I wish to show it. But I don't mind editing a config file or similar in Ubuntu to show it again if need be. So how can I do this?

  • Dual boot Windows 8 and Ubuntu 12.10 across a reboot

    - by AK4749
    My Setup: I have two separate SSDs, and each contains an independently bootable OS - W8 and U12.10. From my extremely limited knowledge, this means each has a functioning EFI partition(?). My default boot order (GA-Z68XP-UD3P mobo with UEFI firmware update) boots the UEFI partition containing windows first, but if I enter the BIOS I can select the "ubuntu" entry to successfully boot ubuntu. Both drives are GPT, and are EFI boots. What I want to do: Reboot Windows 8, re-enter W8 (this is happening now due to the default boot order). What I want to change, however, is to boot into Ubuntu if i reboot from ubuntu. Essentially, I would like to work within one OS unless I consciously choose otherwise. Normally, I would not even ask to something I thought was impossible, but... Why I think this is possible: When trying EasyBCD to add ubuntu to the W8 UEFI bootloader, I noticed an "iReboot" addon or something that allows you to select which OS to boot into from within the OS. Note that I ended up not using the NeoGrub entry to chain Ubuntu off the W8 bootloader because I couldn't get much help with it. Is this possible? Have I had too much coffee and gone insane? Thank you all for your time, AK

  • Boot stuck at blinking cursor before GRUB - only works via BIOS boot menu

    - by delta1
    I have a new box running Debian Squeeze. Grub is installed on /dev/sda, but when booting up I just get a blinking cursor, before the Grub menu. I can only boot to grub successfully when I choose boot options (during post) and select that specific drive! I have made sure the correct drive is set to boot first in the BIOS. So Grub works, but the system won't boot to that drive automatically? Any ideas on what could cause this? Drives sda/b/c are all 2TB (sda runs the system with b/c as raid device md0) with the following partitions: $ cat /proc/partitions major minor #blocks name 8 0 1953514584 sda 8 1 977 sda1 8 2 9765625 sda2 8 3 6445313 sda3 8 4 1937302627 sda4 8 32 1953514584 sdc 8 16 1953514584 sdb 9 0 1953513424 md0 but # fdisk -l /dev/sda gives WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

  • Bless doesn't fix white boot screen boot delay for single-boot Xubuntu 14.04 on Macbook 4,1

    - by elephant
    I still have a 30-second delay on the white boot-up screen before Xubuntu loads after trying various combinations of bless --device as recommended here: https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation#Avoid_long_EFI_wait_before_GRUB I wonder if anyone has experienced this before, or can point me to some good steps for troubleshooting this issue? I have cycled my macbook dozens of times, it would be great to be able to boot quicker. I am single-booting Xubuntu 14.04 (no Mac OSX partitions or any other OS, just a GRUB partition at sda1, a main partition at sda2, and a swap at the end of the drive). Suggestions very appreciated.

  • Boot failure randomly. Can someone help?

    - by desgua
    I often get stuck at the boot on battery. I can suspend and hibernate without any trouble (even on battery). If I plug the energy cable everything goes right most of the time (edited June 13). Adding "acpi=off" doesn't solve the issue. Disabling power save from LAN at BIOS doesn't solve this too. Memory test seems to be ok: I can even compile a kernel without a problem: Has someone a tip for this? (I have the same questions marks in my mind as the image shows if not more :-/ ) obs.: this is an upgraded installation from Natty alpha. edited I (May 22): I've installed a brand new final 11.04 and got the bug again. edited II (June 13): I thought it was solved but it is not. After spending eight days off, the same problem happened even with the power cable connected. I had to reboot about 6 times until success. edited III (June 14): I can boot (even with battery) if I disconnect the cable and take off the battery for a few seconds. This lead me to conclude that maybe something is kept into memory of some hardware. Maybe or maybe not related but I also have touchpad issues (jumps) with this machine. edited IV (June 25): I opened gconf-editor and went to apps gnome-power-manager and disabled everything possibly related to suspend or hibernate. No help. Also I grabbed a Fedora live usb pendrive and got the same problem: So I think it is a hardware problem related issue.

  • Neverending issues with grub (ubuntu 14.04 on ASUS with Win8 dual boot)

    - by Mariana
    This is the most frustrating issue I have ever run into using Ubuntu and Windows in the same machine. I have an ASUS K46CB, 6GB RAM and preinstalled Windows 8.1 64-bits. I have successfully installed Ubuntu 14.04 LTS, also 64-bits. To do so,I followed this tutorial whenever possible. I only failed on the disable secure boot part: there is no 'Secure-boot' or even UEFI mention in my BIOS! Screenshots from other BIOS of the same model show the option under Boot, but in mine there is absolutely none. Because of this, I cannot boot into Ubuntu. The computer loads straight into Windows. I tried running boot repair, but got an error (i can show the log, but it's pretty long). Does anyone know how to fix this issue? UPDATE I reinstalled Ubuntu. Same problem, goes straight to Window. Boot-Repair informs me that i am using Windows in Legacy mode. It excecuted with no errors this time, but after restarting GRUB was still missing. I can't turn off Secure Boot yet. UPDATE I tried using Boot Repair to install grub on a boot-grub 1mb partition. Still boots straight to windows. I feel like punching something

  • Problem in multi booting Ubuntu 12.04 with existing Windows XP, 7 and 8 in 500GB HDD with 5 Partitions

    - by Dhruva
    Here's my case. I have 500GB HDD with 5 Partitions with XP, Windows7 and Windows8 RP in the first three. As per one of the instruction I've seen in this forum, I did shrink my 4th Partition to create a 30GB unallocated free space to install Ubuntu 12.04. But, when next I'm trying to boot the Ubuntu CD and choosing "Something Else", its only recognizing my 500GB HDD in whole as "/sda" and not reading the free 30GB space separately to install Ubuntu in it as suggested in the instruction mentioned in this forum. I've also tried to install in from within Windows7, by mounting the Ubuntu ISO file and using the .exe file and instruction thereupon (choosing free drive, user name, installation size, etc.), but that also failed after the PC restarted to continue the installation, showing as error for file extension, partition something error. One thing to be noted that the PC I'm trying to install Ubuntu in it is my Home PC and doesn't have any internet connection. Hence, no updates or otherwise online help. What shall I do?? Kindly suggest. Sorry if I made some grammatical mistakes as English is not my first language. Thanks in advance.

  • Possible boot conflict?

    - by Evan Kroske
    I was installing Ubuntu on a computer on which Windows XP was already installed. The computer has multiple hard drive bays, so I decided to remove the XP HDD and install Ubuntu on a blank HDD when it was the only HDD in the system. Unfortunately, if I now try to boot Ubuntu with the Windows XP drive in the second slot, nothing will boot. However, if Windows XP is in the first slot, it will boot fine. Can anybody explain why this happens? When I was checking out the BIOS to see if something was messed up, I discovered that when Ubuntu is in the first slot, the BIOS doesn't recognize any HDDs. However, if XP is in the first slot, the BIOS recognizes both drives. Any hypotheses about why this happens? Edit: Here's the setup. I have an old server with seven SCSI HDD slots. I have five identical 68 Gb SCSI drives, but I can keep only two plugged in. XP is still installed on the first drive, but I reinstalled Ubuntu on the second drive and had Grub overwrite the XP bootloader on the first drive. Now, the setup works fine, and I can use Grub to load either XP or Ubuntu. However, if I plug in another identical blank HDD in the third slot, the computer recognizes only the XP drive and doesn't boot. Grub starts to load, then gives me a "disk not found" error. Running ls from the grub rescue prompt only shows one drive with two partitions. I guess this is a BIOS problem, but I'd still like to know what triggers it. What about a blank drive could cause the BIOS to freak out?

  • Compaq Presario R3000 randomly fails to boot on 11.10, 12.04, 12.10

    - by dlfuller
    I’m trying to figure what to do with random failures to boot. My old HP Presario R3000 with AMD Athlon XP-M sometimes boots, sometimes hangs with a blank screen during boot, and sometimes hangs on shutdown. After a few boot attempts it will finally boot to the GNU GRUB screen where I usually can select Recovery Mode, then select return to a normal boot, and the thing will startup and function normally. The pattern is not repeatable and seemed to start after upgrading from 11.04. Clean installs of 12.04 and 12.10 on newly-formatted hard drives make no difference. If this might be a clue, hangs on shutdown often stop at a line with: “pcmcia_socket pcmcia_socket0: cs: IO port probe 0x3000-0x7fff: excluding 0x3000-0x30ff 0x3400-0x34ff 0x3800-0x38ff 0x3c00-0x3cff”. I did try the “acpi=off” modification from 11.10 randomly fails to boot on Compaq Presario R3000 with no change in these random boot failures. Any suggestions sure appreciated.

  • How do boot sectors and multiple drives works?

    - by GiH
    I don't fully understand the concept of a boot sector, I was hoping someone could clear this up for me. If you have two hard drives, with an OS installed on each, does each drive have its own boot sector? Does each drive need an MBR partition? I've got Linux and Windows on two separate drives. I've had issues when installing Linux and grub, and now I've finally decided to use the Windows bootloader to start up. Would Windows have gotten rid of grub when i used /fixmbr or does it stay there on the boot sector of the other drive?

  • Operating System not Found after installing Ubuntu in a Sony Vaio

    - by diego8arock
    I just bought a Sony Vaio SVS15115FLB that came with Windows 7, after enjoying the PC graphic power for a little, I decided it was time to install Ubuntu 12.04. First, I inserted a USB stick, reboot, press F11 but a message saying that no OS was found on the USB, so then I used a live CD. It booted fine and I installed Ubuntu, then when it was time to restart the PC, it didn't boot to GRUB but it went straight to Windows and it began an startup error and was looking for a solution, after it was done, it restarted and then it booted again to Windows and to the same start up error solution thing. I freaked out, so I booted again the Ubuntu live CD, and installed Ubuntu over everything, after it installed I rebooted and then a message appeared saying Operating system Not Found, and I have no idea why. So I Googled again and found this post on Boot Partition, I did everything exactly on that post, but it didn't work (by the way, this was the message): The boot files of [Ubuntu 12.04 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. It appeared the first time, then I did it all again and then it was gone. I rebooted and nothing, the same Operating System not found message appeared. So I decided to create a partition for Windows, hoping for something, but the message still appears. I really have no idea what to do, but there is something odd, if I insert the USB stick containing Ubuntu 11.10, the message that says that there is no OS in the PendDrive flashes for a fraction of a second and the boot straight to Ubuntu 12.04 without problems (and booted to Windows when I installed it, ignoring Ubuntu), right now I'm using it like that, but its pretty annoying. Can anyone advise me how to fix this? I'm no expert on this kind of things (boot, GRUB, recovery and stuff like that).
