• Help with dual booting Windows 8.1 Professional and Ubuntu 13.10

  - by user1292548

  I recently installed a clean version of Windows 8.1 Professional on my Lenovo Y500 (with Samsung 256GB 840 Pro SSD). I have Windows all set up and running normally. I am trying to dual boot Windows 8.1 and Ubuntu 13.10, but the installation procedure don't allow me to either "Install alongside..." or shows my SSD partitions correctly when I chose the "Something Else" option. I have created a 25GB partition of free space in the Windows disk manager, but on the installation screen on Ubuntu, it shows the whole drive as a free space. I have tried installing with a burned .ISO disk and a bootable USB, the results are the same for both. Windows Disk Management screen: http://imageshack.us/a/img855/9504/59zu.jpg The Ubuntu installation screen: http://imageshack.us/a/img62/2712/9g6i.jpg I've ran into this problem before when trying to dual boot Ubuntu and Windows 7 Professional a month ago. But I gave up and never resolved the issue. --EDIT-- I tried what Eero Aaltonen suggested, and this is my result: ubuntu@ubuntu:~$ sudo parted /dev/sda print Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? yes Model: ATA Samsung SSD 840 (scsi) Disk /dev/sda: 256GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags ubuntu@ubuntu:~$

• Attempted to dual boot with Windows and now can only run Ubuntu

  - by Zeusoflightning125

  Very recently, I decided to attempt to dual boot Ubuntu with my already installed windows 8. Everything worked perfectly, I manually set up disk partitions (this is all on 1 hard drive), and it loaded up Ubuntu fine. HOWEVER, now when I try to load up my computer it only has 2 options in the boot menu and both just load up Windows (both were something related to hard disk). I also can only boot from legacy hard disk things. (I already only was able to aside from my USB that I installed Windows from) The Windows files are still accessible from Ubuntu, but I cannot just load Windows. There is no option to. I also don't have the 2 buttons for each operating system I was expecting. I can only select the thing to load from BIOS. So, my question is, how do I load the Windows partition on my hard drive? I'm sorry if I'm a bit clueless I am just new to both Linux and dual-booting.

• Dual Boot ubuntu 12.04 and Windows 7 on two separate SSDs with UEFI

  - by Björn

  With the following setup I get a blinking cursor after installation: Windows 7 64bit installed in first SSD (not UEFI, using MBR) Installation of Ubuntu 12.04 64Bit on gpt partioned disk seems to work without problems but does not boot. It stops with a blinking cursor. I used the partitioning scheme described here. Partitioning scheme: sdb1 efi boot partition fat32 sdb2 root btrfs sdb3 home btrfs sdb4 swap Is it possible to mix uefi BIOS with MBR and gpt when using two separate SSDs? I tried grub2 into a MBR as well but it would not install there...

• Chainload boot of Ubuntu installed on 32GB SD card from legacy Grub boot on USB

  - by Gary Darsey

  I have Ubuntu installed on a 32 GB SD card (in the Storage Expansion slot on an Acer Aspire One) with Grub2 installed in the same partition. I boot into legacy Grub on a USB drive and would like to boot by chainloading Grub2 from Grub (kernel/initrd or symlink booting would also be fine), but I haven't figured out how to do this from legacy Grub CLI. Output from blkid for this partition is /dev/mmcblk0p1: LABEL="Ubuntu" UUID="7ceb9fa7-238c-4c5d-bb8e-2c655652ddec" TYPE='ext4" / fdisk -lu information Boot indicator ID 83. Related entries in grub.cfg: search --no-floppy --fs-uuid --set-root 7ceb9fa7-238c-4c5d-bb8e-2c655652ddec linux /boot/vmlinuz-3.5.0-17-generic root=UUID=7ceb9fa7-238c-4c5d-bb8e-2c655652ddec... initrd /boot/initrd.img-3.5.0-17-generic I can't seem to replicate this in legacy Grub. Is there any way get Grub2 to chainload? How do I set root with UUID in legacy Grub? I prefer to boot from USB. Would Grub2 on USB (copying the grub.cfg generated during installation) be an option?

• Reinstalling GRUB2 on Ubuntu 12.04 | Windows 7 dual boot after Windows reinstallation

  - by Shasteriskt

  So I had the perfect Ubuntu 12 / Windows 7 dual boot set-up -- until I had to re-install Windows 7. After the deed, GRUB2 was of course wiped out, thus my Ubuntu installation is rendered inaccessible. I have tried these steps: mount /dev/sda5 /mnt #This is where my Ubuntu installation resides. mount /dev/sda1 /mnt/boot #Indicated by the `*` under `Boot` when doing `fdisk -l` mount --bind /mnt/proc /proc mount --bind /mnt/sys /sys mount --bind /mnt/dev /dev sudo chroot mnt sudo grub-install /dev/sda sudo update-grub #Then unmounted everything... Unfortunately, only my Windows 7 has been detected and the Ubuntu entries never appeared in the prompt. Only my Windows 7 installation (/dev/sda1) is available in the GRUB2 menu. How can I rectify this?

• Ubuntu install and dual Boot with Windows 8 UEFI

  - by Jose Maria

  i have Ubuntu 12.04 x64 ISO, i load it on a Fat32 USB. My notebook has a hdd with GPT where i installed Official Win 8 Pro x64 (final versión), I partitioned the whole hdd, previously of win 8 install, and bios is set with UEFI boot. My BIOS notebook doesn't support SECURE UEFI BOOT. So I boot the notebook from USB and the Grub runs OK showing whether to run Ubuntu live or to install, but neither one neither two works, when I choose then the screen shows black and nothing happen, it doesn't start/loads the install program. I've try whether to prepare the usb with unetbootin, or just direct copy/paste the files onto the USB. I also have try WUBI, but neither with success, it launch an error when ending.

• Can no longer boot with rEFIt and Grub on early 2006 MacBook Pro

  - by Don Quixote

  I don't know what happened to cause this. I have Snow Leopard, Ubuntu 11.04 Natty Narwhal and Windows XP SP3 on my early 2006 MacBook Pro. It is a Core Duo unit, NOT Core 2 Duo, so it is 32-bit only - Model Identifier MacBookPro1,1. I use rEFIt 0.14 for my boot menu. For some reason neither XP nor Ubuntu would boot anymore. I'd just get a black screen with a rapidly flashing underscore in the top-left corner. Having both those OSes failing to boot suggested a problem with the boot loader in my MBR. The rEFIT partition tool verified that my MBR partitions were still synced with my GPT partitions, so I rewrote my MBR partition table with fdisk while booted from Parted Magic: # fdisk /dev/sda (fdisk warns about the disk having a GPT. I press on anyway.) p (Print the existing partition table to make sure it's OK.) w (Write the old partition table back to disk. This also writes a new MBR boot loader.) After this XP would boot but Ubuntu would not, with the same symptom. Now I used update-grub while chrooted into Ubuntu from Parted Magic: # mount /dev/sda3 /mnt # mount --bind /dev /mnt/dev # mount --bind /sys /mnt/sys # mount --bind /proc /mnt/proc # chroot /mnt Chroot issues some warnings about not being able to identify some group IDs. I don't know why that happens, or whether it is a problem. At this point while I am still booted off of Parted Magic's kernel, I am running from Natty's filesystem. # update-grub Update-grub detects each of my operating systems then claims to complete successfully, but still won't boot. I asked this same question over at rEFIt's Sourceforge support forum but there have been no replies yet. I also Googled quite a bit, and see many who have the same black screen problem, but none of their situations seem quite like mine. Thanks for any help you can give me. -- Don Quixote

• How to fix the boot set up?

  - by Chris

  I got two OSes in my PC, Ubuntu and Windows 7. Until yesterday Windows 7 was on top of my dual-boot menu list, but I wanted to change it, so I went inside Windows configurations and put Ubuntu first, but I also set the time to 0 because I thought I could access Windows through Grub. But what happens is that after I upgraded Ubuntu to 11.10, that screen with boot options don't show Windows 7 anymore. I went online searching for a solution to my problem, most of them told me to configure some Grub options and others to use programs to do it. I've done them all and still can't access Windows 7. Just in case my problem is not clear yet, this is how was my boot order before I messed it all up: Windows 7 Ubuntu with a time of 10 secs to choose between both. This is how I wanted it to be: Ubuntu Windows 7 with 0 time to choose, but, inside Ubuntu I could access Windows through that Grub screen. But this is what happens: Ubuntu Windows 7 0 time, so it don't let me choose anything and jumps inside Ubuntu then inside Ubuntu grub doesn't show up anymore (black screen) and it starts Ubuntu normally. I tried to fix this many times from different ways inside Ubuntu but nothing worked, also when I try do something and then upgrade my grub with sudo upgrade-grub it shows this message: Generating grub.cfg ... Found Windows 7 (loader) on /dev/sda1 Skipping Windows 7 (loader) on Wubi system Found linux image: /boot/vmlinuz-3.0.0-12-generic Found initrd image: /boot/initrd.img-3.0.0-12-generic Found linux image: /boot/vmlinuz-2.6.38-12-generic Found initrd image: /boot/initrd.img-2.6.38-12-generic done Thats why in the title I said it could probably be my WUBI messing all up. Anyone heave a solution for this? Do you need more information? I have a netbook so I cannot use the Windows Repair CD.

• Dual booting Windows 7 & 8.1, using the Windows 8 Startup Options Menu, when Windows 8.1 is already installed and you want to add Windows 7

  - by Josh

  There are many excellent guides out there that explain how to dual-boot Windows 7 & 8. However, they are written for people starting with a Windows 7 installation and add a Windows 8 installation to separate partition. From what I'm reading, following this procedure will result in Windows 8 installing and configuring the Startup Options Menu with an option to boot Windows 7 & 8. However, in my situation I have a Windows 8.1 machine that I want to install Windows 7 on, and enable dual-boot, where I can use the Startup Options Menu to select the OS to boot. I haven't been able to determine how to do this. From everything I've been able to find, it looks like if I install Windows 7, it is going to take over the boot loader process, and I won't have access to the Windows 8 "Startup Options Menu." This answer suggests I boot to VHD, but notes a drawback: You can't do this if the C:\drive is encrypted using ANY encryption shceme. Be that BitLocker or 3rd party. The location of the .VHD file you are booting to must reside on an unencrypted volume. Well, that's a bummer, because that's exactly what I wanted to do--I wanted my Windows 7 partition to be encrypted, and my Windows 8 partition to also be encrypted. The idea being that when OS was booted, it was completely locked out from accessing data on the other OS's partition. At this point, I'm thinking my only option is to install Windows 7, and then re-install Windows 8, which will give me the dual-boot option... am I right? Or is there a way to make this work. I'm thinking that I would need to figure out a process like this: Configure the Windows Startup Options Menu with a "blank" entry for Windows 7, pointing to an empty partition Insert the Windows 7 installation media, install Windows 7, and somehow restrict it to that partition (i.e., prevent it from "taking over" from the Startup Options Menu" Is this possible, and if so, how can I accomplish this? My concern is that if I simply install Windows 7 to a separate partition, Windows 7 will take over the entire boot process and I won't be able to get to my Windows 8 installation any more.

• Computer will not boot - disk read error - cannot boot from HD or DVD

  - by Grant Palin

  This is a 3 year-old system: HP a1640n. There have been no issues with it in the past. I added a video card 2 years ago, and more memory 1 year ago, both without issues. There haven't been any recent hardware changes. I did install Win7 in Oct., but there were no issues with that either. I used the computer fine two nights ago, and turned it off. Yesterday, I tried to turn it on, and got the error: "A Disk Read Error Occurred. Press CTRL ALT DEL to restart" So I restart, see the initial start screen (HP) and enter the BIOS. The hard drive and dvd drive appear to be listed, but the names are gibberish text. I tried putting a Windows disk in the dvd drive, and continued with the boot, but the disk did not get recognized. Even though the BIOS was set to check for optical media before the hard drive. Back to the error screen. If the computer would boot from a cd or dvd, I would just figure the hard drive needed replacing. But both being problematic worries me. Is this a matter of replacing both the hard drive and dvd drive, or might it be an indication of a bigger problem? Thanks for any advice.

• Dual boot - 12.04 installed first

  I have found many guides with how to install windows and ubuntu in dual boot mode, but none from the perspective of a Ubuntu user. Unfortunately Wine or OpenOffice do not display a document that I am working on properly so I am forced to getting windows back temporarily.

• Need Help with partitions and such Dual Booting 13.10 w/ windows 7

  - by Aymax

  so I've spent the past couple days freaking out about this and looking for answers, and I decided to resort to asking on forums. probably should have before I wasted 2 entire days. so I am trying to DUAL-INSTALL Ubuntu 13.10 with my x64 Windows 7 home premium computer. I have 6 gb of ram, 1TB hard drive, and a 3.3GHZ dual core processer (just in case it matters). I've managed to figure some things out. I've burned the ubuntu files onto a DVD, and I have been able to successfully run it off the disk. I also shrunk my Windows partition by 120Gb and partitioned that for Ubuntu (all using the windows Disk Manager). Problems: When I turn my computer on with the DVD in the tray, the computer cant find windows. it flashes a screen real quick that says something about not being able to find an operating system, and then goes to "grub" and asks what i want to do with Ubuntu. this scares me, because I don't know if that means that I will not be able to boot windows if I install Ubuntu. The Ubuntu 13.10 installer does not detect my Windows operating system. I only have the options to Erase everything on my drive, or "something else." I choose that, which brings me to 3 I don't understand the partition table. I have no idea which drive im selecting to install stuff on, much less which one to select. I tried to tell by the amount of memory partitioned off, but none of the numbers seem to be accurate. Plus, all the names are dev/sda(#). I know Ubuntu knows the name of my partition, because on the sidebars it shows the names of the different drives, including the partition I made; so why don't they use the names? I have no idea what I'm going to be erasing. I've read that I should know which is which by the file system type, but they are all NTFS, including the one I made. my only other option was FAT, none for EXT2 or any of that like people said to do. My main concerns are that of accidentally erasing windows or not being able to access windows. any feasible solution is helpful, weather it helps me with the install or to make Ubuntu see windows. I realize this question has been asked much, but i have found no feasible answers so far. I am relatively new to this, and have never installed an operating system before, so I do not know most of the jargon. please keep it relatively simple, please. I am not a programmer. Thanks.

• Windows XP with Ubuntu 14.04 on 2 separate hard drives

  - by maplenet2

  I am new to Ubuntu. I have Windows XP Professional 32-bit on one 300GB IDE hard drive and Ubuntu 14.04 running on another 61GB IDE hard drive, and I cannot get my Windows XP to boot with Grub! When I select Windows XP from the boot menu, Grub just restarts my computer. The computer I have with those two hard drives is a Dell Optiplex GX240, so the hardware is old, and its BIOS won't let me change the boot priority on the two IDE hard drives. What can I do now? Is there a step I missed when installing Ubuntu? Can I edit Grub to boot Windows XP without messing with the BIOS? Do I have to downgrade to an older release of Ubuntu to make it work? I am willing to reinstall Ubuntu, if that's what it takes.

• 12.04 Booting into Terminal

  - by user170796

  To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.
