    Exclamation Booting issue on Ubuntu 13.04

    Hi!
    I had some issues with my win 7 so I decided to change it to Ubuntu.
    I used a live USB key to get to the installation manager or whatever it is called.
    At this point there is no problem. I chose the delete everything and install linux option and went on 'til the end.
    The fact is that when i take out my USB key and boot, I receive the message: Reboot and select proper boot device.
    This even though I have only one hard disk. Choosing this very one in the Bios won't change a thing.
    Also, when I let my USB key on my computer, it somehow manages to get to the ubuntu loading page and turns to console mode with the text "Kernel panic: Not syncing attempted" on it.
    It seems my live CD is fine and that it corresponds to my computers settings (X 64).
    I tried it numerous time ( no data to lose so...) using the "take all disk option" and the other one by creating a boot partition, a /, a /home (both in ext4) and a swap.
    It always end up the same way.
    As for now i'm using the live CD to post this, I can't use any windows tools (which by the way are the one that led to ir crashing).
    This is what gparted shows of the job done by ubuntu install. I don't get the use of Lvm2 pv file sytem. When i look at the file system support this looks wrong.

    Well, since I haven't got a clue about what's goin' ont, i'd be really delighted to receive some help.
    I don't know the console's command to get more info so I'll will give a try later.
    Thanks anyway and sorry for my english!

    I do not know encryption, but it uses lvm for full disk encrytion.

    Post the link to the BootInfo report that this creates. Is part of Boot-Repair:

    I do not know LVM and whether that really works with UEFI or not.

    You have grub in separate /boot partition so you should get grub menu, but with one system installed it will not show it by default. If you hold shift down from UEFI/BIOS do you get menu. Some with UEFI have to use escape key instead.

    Some systems need extra boot parameters which you need to add onto grub menu linux line.

    You can boot Ubuntu with BIOS on gpt partitioned drives but then need a bios_grub partition instead of the efi partition. A bios_grub is only 1MB unformatted space anywhere on drive. You can set bios_grub using gparted and manage flags.

    Re: Booting issue on Ubuntu 13.04

    Hi! thanks for your reply.
    I tried the shift down thing as well as escape and it doesn't do anything.
    What seems wrong to me is that I can get to the grub menu when my Usb device is in. May Ubuntu have installed the boot or some needed files on it.
    Also when I get to the Menu i can change the language and that's it. F# keys won't work so I can'tt access the other options.
    Finally the lvm part is bothering me as I can't change the partition in another system file nor modify its size.

    Looking as the many issues I have I will probably try a new install ( another one..) and try to partition everything by myself.
    Can you confirm what I need?
    A ext4: / (40 go)
    A ext4: /home ;not necessary but I want one (454 go)
    A swap: ( 5 go) (I have 4 of DDR 2 or 3)
    A bios partition with the boot flag ( 1 mo)
    ?

    Re: Booting issue on Ubuntu 13.04

    Those partitions should be ok. I use 25GB for / as I put all data in other partitions and with lots of apps use about 9GB of the 25GB.

    I would leave efi partition in case later you want UEFI. It is difficult to add a partition at the beginning of the drive later. Be sure to keep it gpt, not MBR(msdos).

    If drive is only going to be Ubuntu (never Windows), I would suggest using gpt not MBR as the partitioning scheme. You then do not have any logical partitions, they are all primary and it has a backup in case of problems. You do have to create a tiny bios_grub partition to correctly install grub2's boot loader to the drive.
    If using gpt with BIOS create a 1MB bios_grub partition with no format. I used gparted and selected gpt under device, advanced & select gpt over msdos(MBR) default partitioning....

    Windows only boots in UEFI mode from gpt partitioned drives.

    Re: Booting issue on Ubuntu 13.04

    So it would be:
    All primary partitions:
    sda1: efi ; 1 mb
    sda2:swap ; 5 gb
    sda3: ext4: / ; 25gb
    sda4: ext4: /home ; 469 gb
    sda5: BIOS booting reserved area ( translated from french): 1 mo. !!! Is this really the bios grub partition????? (Just wanna be sure about it)
    Can I really create more than four primary partitons in one hard disk?
    Is that it?

    Re: Booting issue on Ubuntu 13.04

    The efi needs to be 250 or 300MB FAT32 and a bios_grub is 1MB unformatted.

    With gpt you can only have 128 partitions, there is only one type so in effect they all are primary.

    In a GPT partition map, the 31 kiB area after Master Boot Record where GRUB is usually embedded to, does not exist. When GRUB can't be embedded, its only option is to use blocklists, which are unreliable and discouraged. Thus, you must make a separate "BIOS boot partition" to hold core.img. BIOS Boot Partition only needs to be about 32 KiB in size, although in most cases make it 1 MiB because of partition alignment issues. It can be anywhere on drive and has no format.

    Re: Booting issue on Ubuntu 13.04

    Hi.
    So I made it like this:
    25 gb ext 4 : /
    436 gB ext 4: /home
    237 mb: fat 32 : boot
    6 gb: swap
    1 mb: bios grub
    And I still have got the same problem that I used to have.
    Which means that the computer will start and show the bios (F2 choice page) (not the grub one) and then write "reboot and select proper boot device".
    I really don't get it anymore. I have Bios grub as well as a boot partition, the / and swap ones as well. What more doest it needs?
    Well, whatever. I WILL have Ubuntu on my computer.
    So, here is the last link:

    Thank you.

    Re: Booting issue on Ubuntu 13.04

    You are still trying to boot in UEFI mode. You need grub installed to protective MBR and UEFI set to BIOS/CSM/Legacy not UEFI.
    Boot-Repair should convert install to BIOS mode by uninstalling grub-efi and installing grub-pc which will put grub2's boot loader into the MBR. Then you have to have BIOS use MBR not efi partition.

    It can convert from/to BIOS or UEFI.
