• Windows Boot Manager, linking a 'device' to boot linux

  - by TheCompander

  I'm attempting to boot linux on a UEFI-GPT machine with a Windows Boot Manager (WBM). So far I have installed Archlinux (Arch) with Grub. The grubx64.efi is successfully on my windows boot partition and I can see the option to use it in UEFI-BIOS, selecting this loads grub and I'm able to get into Arch fine. I have noticed that in the Windows Boot Manager, selecting from the splash screen, 'Change defaults or choose other options' 'Choose other options' 'Use a device', shows the boot options as in UEFI-BIOS, in my case grub shows as 'Linux'. Selecting 'Linux' reboots the computer and loads grub then Arch. Is there anyway to use this entry for the device 'Linux' to show directly on the WBM splash screen under the entry for Windows 8.1? Ideally i'd like the 'Arch Linux' to link to the 'Linux' device. Guidance with bcdedit appreciated, thanks in advance.

• Windows 8 won't boot after Boot Repair

  - by Rudolph Gottesheim

  I've got a Sony Vaio laptop. Until yesterday I had Windows 7 and Ubuntu 12.04 installed. Today I upgraded to Windows 8, which killed my OS selection screen. So I booted to Ubuntu 12.10 from a USB stick and ran Boot Repair. This recovered the GRUB screen and let me boot into my Ubuntu 12.04 installation, but now I can' boot Windows 8. When I select the option that booted Windows 7 before, it looks like it wants to start Windows 7 (sic) again (black screen, with the text "Windows is loading" or something), but then reboots the machine after a few seconds. I'm sure Boot Repair can fix this, but I know far too little about the whole booting thing to know the right settings for it. Here's my boot repair report thing.

• Add an entry for Ubuntu on Windows 8 boot loader

  - by John

  I have installed Ubuntu 12.10 by creating free space in Windows 8 and then using that space to create 3 partitions, one for SWAP, one for GRUB (mounting point is /boot) and one for the actual OS. I did this so the Windows 8 boot loader wouldn't be overwritten in case I ever wanted to remove Ubuntu. I can still boot into Ubuntu if I select the boot loader from the BIOS. I want to add Ubuntu to the Windows 8 boot loader and I've been told to use EasyBCD. The issue with that is it doesn't actually direct Windows to the GRUB file, but rather to something like autogrub0.mri. I have found another programme called Visual BCD which will allow me to actually set the bootloader paths and drives. From here, I don't quite know what to do. I believe I have it set to the correct drive but I don't know if I'm directing to the right file. I think it's /boot/grub/x86_64-efi/grub.efi. I don't know if that's the right file, if I need to remove /boot or if the / need to be \ as that's what Windows uses. Sorry for such a lengthy post, please help!

• Will BIOS boot mode Ubuntu install be able to boot when firmware "Fast Boot" is "Ultra Fast"?

  - by Pro Backup

  I have an AsRock mainboard with UEFI BIOS P1.50 02/14/2014. The firmware "Fast Boot" option is set to "Fast", Boot Option #1 is set to "AHCI P4: OCZ-VERT...": this is BIOS not UEFI boot. This boot disk has an MBR partitioning scheme (# parted -l | grep Partition\ Table:). Therefore Ubuntu 14.04 is installed in BIOS/CMS (Grub-PC) mode. The Ubuntu boot process ends in a text console (no GUI). There is no external graphics card in use. The stock Ubuntu kernel is replaced with Ubuntu supplied mainline 3.16.0-031600rc6-generic. dmesg outputs lines containing BIOS, like: SMBIOS 2.7 present Calgary: detecting Calgary via BIOS EBDA area Calgary: Unable to locate Rio Grande table in EBDA - bailing! [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored BIOS EDD facility v0.16 2004-Jun-25, 0 devices found The ASRock BIOS it selves display this help text for "Ultra Fast - Fast Boot": Ultra Fast mode is only supported by Windows 8 and the VBIOS must support UEFI GOP if you are using an external graphics card. Please notice that Ultra Fast mode will boot so fast that the only way to enter this UEFI Setup Utility is to Clear CMOS or run the Restart to UEFI utility in Windows. Assumptions: I suspect after changing UEFI setting "Fast Boot" to "Ultra Fast" that the machine will no longer boot into Ubuntu's console. I expect when first exchanging "Grub-pc" with "Grub-efi", that the machine will still be able to boot to a grub menu (thus allowing to change the "Fast Boot" setting back to "Fast" without clearing CMOS). Are these two "Fast Boot" assumptions correct, and/or, may I expect Ubuntu 14.04 running mainline kernel 3.16rc6 and Grub-efi to still boot to console after enabling UEFI Ultra Fast Boot?

• error: no device connected

  - by Prabath Swarna

  I did a fresh install of 12.04 and it went fine, worked on it for several days, but one day the browser crashed and i reset the machine, after that I get this error when i boot; error: no device connected error: no device connected error: no device connected error: no device connected This comes after the BIOS confirmation, and it stays for about 30 seconds, then the grub menu comes and when I selected the default the screen becomes purple and stays like that for a whole Minuit. I thought maybe that is because I have 500GB HDD so i ran the boot-repair, It did nothing at all. I'm sure I did the boot-repair thing right, sorry I forgot the paste URL. If i reinstalled will this error persist.

• How to fix GRUB on dualboot with Windows7 and Ubuntu?

  - by b_oliv

  I am a relatively recent user of Linux. I had several releases of Ubuntu installed on my laptop working in dual-boot and never had any issues. Recently, I installed openSUSE because I thought it would be necessary for an assignment at my university. It turns out it wasn't so I returned to Ubuntu and decided to burn the new .iso to a CD and install it. The problem is that during installation process I almost for sure messed up with the partitions and now, whenever I tried to load Windows 7, it will tells me that a required device is inaccessible. So, I reinstalled Ubuntu again and now all I get is that I am redirected to the GRUB menu without any warnings. I tried creating a Windows Recovery Disk but it gives me Unexpected I/O error. I suspect it is because it was downloaded from the Internet and maybe some files weren't there. I tried everything without success, so I decided to ask here, in the hope I can receive some help and also learn how to help others with it in the future. Here it is my boot info summary: http://paste.ubuntu.com/1344990/ Also, I might add, that on the boot-repair advanced options, the box repair Windows boot files is "locked", so I can't check it. EDIT: Apparentely, the box is locked, because, from what I understood after reading the boot-repair information, everything is fine with my windows boot-files... I still need some guidance though

• Control which os is booted on multi-boot system

  - by mooware

  I am setting up a server with multiple operating systems for the automatic testruns of my company's product. I'd like to be able to control with a script which OS boots up after a restart, so I could say for example "after the windows run, boot into linux". I thought of using the windows bootloader for all OSes, because it should be easy to just change the default entry in C:\boot.ini to whichever system I want to boot. Is this a feasible way of doing this? Are there better options?

• Dual Boot Ubuntu and Windows 7: BOOTMGR is missing when I tried to boot in Windows

  - by Simon Polak

  So, I don't know what exactly how I managed to delete the MBR record on windows partition. But let me explain what I did next, I ran the ubuntu boot repair tool and now Windows is not even listed in my grub loader. So I went and booted with windows cd and choose repair. Then I ran ubuntu boot repair again via live cd. Here is the log http://paste.ubuntu.com/1426181/. Still no luck. Looks like osprobe can't detect windows on my /dev/sda2 partition. Any clues ?

• 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

• Windows no longer boots on dual-boot system

  - by N Alex

  While trying to delete an Ubuntu partition from my hdd I accidentally rebooted my computer. (Note: the partition was originally made from an existing partition using paragon.) After that when I tried to start the computer I got the GRUB rescue terminal prompt. I wasn't able to do much from that, but I did manage to boot Ubuntu from a USB drive and to run boot-repair. But now when I try to select Windows 7 from the boot selection menu I get the error 0xc0000225. Here is the link to the BootInfo summary created by boot-repair: http://paste.ubuntu.com/1032584/ I have a lot of very important data on my hdd and I would really appreciate your help.

  I had Windows Vista installed on a laptop. I have installed separately Ubuntu, wanting to have a dual-boot system. Now, Ubuntu works OK, but I am unable to boot into Windows. GRUB menu provides me with two entries: "Windows Vista (loader)" and "Windows Recovery Environment (loader)". However, BOTH boot into recovery environment.

• Uninstalling Ubuntu dual-boot bootrec issues

  - by Raymond Standen

  So on my laptop I am currently planning on uninstalling Ubuntu 12.04 so I can upgrade my Windows 7 partition to Windows 8, then install Ubuntu 12.10. My issue being that when I boot the Windows 7 recovery disk, I believe i Need to use cmd to run bootrec /fixboot and bootrec /fixmbr. Now, whilst fixmbr works, fixboot yields me with an error regarding an unrecognised volume. When I turn on my PC now, I am no longer met the GRUB option, so I boot straight into Windows. My question is: As such, do I still need to have fixboot run or can I just format and resize the partitions now even with the error when running fixboot?

• Cannot boot from K/Ubuntu install disk on my UEFI system

  - by user93241

  I just got a new system and have been trying to get it set up w/ Win7 & Kubuntu dual-boot, but I've got a major problem. The BIOS of my motherboard (an Asus Crosshair 990FX) is strictly UEFI -- there is no legacy support mode available. I've been reading up on how to get Kubuntu installed in UEFI mode but no matter what I try I cannot seem to even boot into my install CD/USB key properly. I can get as far as the selection screen ("Try Kubuntu", "Install Kubuntu"...) but this screen starts off not appearing correctly. If I try moving the cursor around it sometimes seems to correct itself and show me my choices. But once I select "Try Kubuntu" it starts loading, the screen goes black and then proceeds to flicker -- about once every 5-10 seconds or so. This continues indefinitely. I've tried this with both Kubuntu & Ubuntu installation media, even the AMD64+Mac Ubuntu variety that is supposed to be a lot more flexible w.r.t. UEFI. The only hint I've had that the system might have booted correctly is a little drum sound that plays when booting from the Ubuntu install disk. Well, that and the fact that when I hit my system's power button it seems to shut down correctly, even ejecting the CD at the end. This might be a video driver issue; my system has two nVidia 550's, one of which is attached to my primary monitor. (The secondary isn't hooked up yet.) I'll keep looking over similar questions but any advice would be greatly appreciated. UPDATE: I've tried booting into my 12.04 install CD twice now, each time using two different options supplied by my BIOS. One seemed to offer the ability to boot into my CD under UEFI mode -- this didn't even produce the initial boot menu. The other method offers the ability to boot into my CD NOT under UEFI mode. This DOES produce the boot menu, but after this point it seems I still cannot get to a proper video mode to see what's going on.

• Cannot boot Windows 7 after installing Ubuntu 13.04

  - by whowantsakookie

  So I boot up my computer after installing Ubuntu 13.04. Grub correctly shows me all available boot options and I am able to boot to Ubuntu. However, when I try to boot into Windows 7, grub hangs at a purple screen. I have an HP laptop. It came with all four primary partitions taken up by the Windows bootloader, the actual Windows partition, one called HP_TOOLS, and another for HP Restore. I was able to back up and delete HP_TOOLS and the recovery partition, and change my disk type from Dynamic to Basic (GParted doesn't recognize Dynamic drives). I then booted into a live session of Ubuntu and made two partitions with GParted: one large partition for storage space that I could use between the two operating systems (sda4), and another extended partition (sda3) which contained Ubuntu (sda6) and it's swap space (sda5). It currently looks like this: I'm not sure if the second paragraph is actually relevant, I just want you to know all the variables in the equation. Thank you in advance for helping this poor noob.

• Cannot boot into Ubuntu after installing Ubuntu 12.04 (with Windows 7 on another partition)

  - by onezanygirl

  I just installed Ubuntu on my desktop which had Windows 7 installed on it. When I restart the machine after completing the installation, It directly loads windows, I don't see the grub menu. I tried using boot-repair using the LiveCD (both recommended fixes AND fixing the MBR), it did not help. What am I missing? I have done this at least 5 other times, on different machines, and have never faced this issue before.

• Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

  - by Al Rowe

  Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

• Resized Ubuntu 14.04 partition will not boot

  - by user292577

  First, a little background info: I intended to install Ubuntu alongside OS X, but I accidentally erased my entire hard drive and was left with Ubuntu alone. Yesterday, I finally tried to create a desperate partition and OS X. I successfully shrank my Ubuntu partition and created ~40 GB of free space. I used gparted to do this. At first I tried to use Internet Recovery to install OS X on the unallocated space I had created, but discovered I couldn't. I went back to gparted and created a FAT partition with that space. I'm pretty sure I actually did this using my Ubuntu partition on my hard drive (the one I had just shrunken), rather than the USB live boot I had used to shrink it. Therefore, at this point, I think my Ubuntu partition was still functioning properly. I went back to internet recovery and used disk utility to turn the FAT partition into a Mac OS Extended (Journaled) [HFS/HFS+] partition. I believe this is probably where the problem occurred. I successfully reinstalled OS X and found it to be fully functioning. However, when I tried to boot back into the Ubuntu partition all I got was a black screen with a little white cursor (it looks similar to a terminal screen/the Mac DFU mode, but I can't type anything into it. Is there anything I can do to repair my Ubuntu partition? If not, can I at least recover the data from it? Thank you for any help.

• How to repair GRUB from backup?

  - by titusjaka

  I have Windows 8 and Ubuntu 13.04 in dualboot. But the problem was that Windows didn't boot when GRUB is set as primary bootloader in BIOS. When the Windows EFI partition was checked as primary, Windows booted well. Then I decided to fix it and installed Boot-Repair. First of all, I made the backup. Then updated the GRUB. The update was successful. But then Windows and Ubuntu didn't boot at all. I've repaired GRUB using live-USB. Now I can boot Ubuntu, but Windows doesn't boot. How can I restore boot partitions from Boot-Repair backup (.zip file)?
