VIRTUALBOX NO BOOTABLE MEDIUM FOUND PC
VirtualBox, stationary Intel PC 32 and 64 bit.In the Virtual Machine window, go to Storage, and medium. Tested it by running under qemu-system-x86_64, qemu-system-i386, This should simply print "Hello!" to the screen if the MBR was loaded, then To restore MBR do: dd if=/path/mbr-backup of=/dev/sda bs=512 count=1

But one has start somewhere.īackup current MBR: dd if=/dev/sda of=/path/mbr-backup bs=512 count=1Ĭreate image from Code TEST below, saved to file test.s by: as -o test.o test.sĬopy the test.img file to MBR: dd if=test.img of=/dev/sda bs=512 count=1 The "set boot flag" is merely a shot in the dark, - and would be surprised That is what theīios_grub is for - to store core.img for GRUB 2. One have to move those GRUB files to another location. It can reside anywhere, but usually on same disk and at offset 512 of MBRĪlso on a GPT system – GPT uses that section of the disk for itself, thus The GRUB module 1 files reside just after MBR and before first partition. Here boot partition is Partition 2 which is system partition with I raw bytes – as in not part of any partition etc. Everything before offset 0x400 on the HDD Like: 0x000 <- Partition table say Partition 2 is activeĠx200 <- core.img from GRUB | In a traditional partition layout (not GPT) you have typically something The sda1 is not a boot partition in the traditional sense, Point being, for whom ever say no "bootable device found", they shallīe satisfied. It could be that your BIOS is doing more then it should and checking theĪFAIK it doesn't matter which one you set as it is not actually used. # Check (could be an asterisk marking boot partition): (g)parted also alter GPT which whan do not want)fdisk : # Toggle bootable: Using GPT that is correct, - but, though it is forbidden, you could try toįlag one e.g. I notice you have no partition marked as "boot".

That MBR of boot disk is corrupted, if MBR ends in 0xaa55 and the MBR isĬorrupt one usually get an other error - or the system simply hangs.Īnyhow. On "No bootable device found." message from BIOS – one can have the case Partition, - which you have, and is big enough, etc., so can't see how that Using GPT the image GRUB loads from within MBR is located in the bios_grub Which disk has rest of GRUB and load that section of the disk into memory – That code, in this case " GRUB - boot", check various bytes of these 512 inĪddition to ask BIOS for various information. Those 512 bytes are the Master Boot Record (MBR). (sector 1), into memory and leave control to it on address 0x00000 of thatĬode. When it finds a disk that has 0xaa55 at offset 510 it loads that section of the disk, Then it looks for devices that are bothīootable and active by order given by CMOS (Your configuration in BIOS – which in turn is given by a Complementary Metal Oxide Semiconductor). When the Basic Input/Output System (BIOS) starts it does a Power-On Self This is not directly related, but only to explain the aa55 comment.

It just showed the message that it coudn't find any bootable devices.īy the way, I tried to install it on this computer.
VIRTUALBOX NO BOOTABLE MEDIUM FOUND PASSWORD
Then I finally chrooted into /mnt, set up some Locales, set a root password and then installed and configured Grub2, exactly as it is explained here.Īt the end I exited from the chroot environment, unmounted the partitions and rebooted. After selecting the mirrors, I installed base and base-devel.Īt the end of the install I generated an fstab. Then I mounted the root partition (sda2) to /mnt, after that also the boot and the home partition (sda3 and sda5) to /mnt/boot and /mnt/home and at the end formatted and activated the swap partition (sda4).

VIRTUALBOX NO BOOTABLE MEDIUM FOUND WINDOWS
I have retried the whole scenario now some times, still it just shows the same message.Īt installing, I have followed the Unofficial Beginner's Guide from the ArchLinux wiki.įirst of all, I wiped the hard drive (on which before the wipe was Windows Vista installed) and put GPT on it by using gdisk. After the installation, it shows the BIOS screen and after that there just comes a message that says "No bootable device found".
