Boot loader with btrfs

[spacerocket]

Hello!

I installed ubuntu 13.10 using this as guide: http://www.linuxbsdos.com/2014/02/01/dual-boot-windows-8-or-windows-7-and-ubuntu-13-10-with-ubuntu-on-a-btrfs-filesystem/

Created swap area and Ext4 journalizing filesystem(which I added as a device for boot loader installation(dev/sda6), mount point /boot) all these from free space. I also created btrfs journaling file system (44,83 Gt visible in my picture) for ubuntu from free space. Then I installed ubuntu and restarted my comp, went to windows 7. There I added the ubuntu 13.10 entry as my picture shows. Now when I click edit boot menu I have windows 7 (default) and ubuntu 13.10. When I restart my computer I get a boot loader where is windows 7 and Opensuse 13.1(my old linux system). The Opensuse 13.1 does not even work anymore(deleted) windows7 works but where is ubuntu 10.3?? Not in the boot loader. Strange?

I do not know EasyBCD.
You may do better here if you want EasyBCD.

If you want to use grub2, not grub legacy as shown in EasyBCD screen?


Boot Repair -Also handles LVM, GPT, separate /boot and UEFI dual boot.:
https://help.ubuntu.com/community/Boot-Repair
You can repair many boot issues with this or 'Create BootInfo' report (Other Options) & post the link it creates, so we can see your exact configuration and diagnose advanced problems.
With UEFI If you run any fixes from Boot-Repair do not say yes to 'buggy' UEFI fix. That is only for systems where UEFI has been modified by vendor to only allow Windows to boot.

Hi!

Thx. I already tried GRUB2 though that didn`t work either. I downloaded boot repair disc from here:http://sourceforge.net/p/boot-repair-cd/home/Home/

Then write image file to disc(CD) with imgburn and start computer with CD in dvd-drive?

[oldfred]

You can create it as a Repair CD or flash drive just like any other Linux repair tools.

Or you can just boot your Ubuntu installer DVD or Flash drive and install to that. (You then have to reinstall with every reboot). With persistence I think you can save download though.

Ok. Now I burned the repair file to my CD and started my computer. Then I chose Recommended repair(repairs most frequent problems).

Then it did something and said:

sda1 ...
sda2 ... (some windows issue)
....

sda6: Filesystem: ext4
Boot sector type: -
Operating system:
Boot files: /grub/grub.cfg

sda7: Filesystem: btrfs
Boot sector type:-
Operating system:
Boot files:
...

Boot successfully repaired. -> Then I restarted my comp and I`m still having the same issue, there is no boot loader for ubuntu 13.10, only for windows. Maybe I did something wrong?

Post link to BootInfo report that Boot-Repair creates.

Hi

Now this link http://paste.ubuntu.com/7203086/ it didn`t fix my boot issue, what`s going on?

Thx

[oldfred]

I do not know enough about btrfs to know issue.
But Boot-Repair and script does not see fstab in sda7, which would be same issue that grub would have.

Are you missing drivers for btrfs? Did they not get installed?
Grub also has extra drivers that you have to load for non-standard file systems.
I do know you cannot use tools like e2fsck as that is for the ext family and must have separate tools for btrfs systems.

Hi

I can`t read all those links. It can`t be this complicated. Now you are saying that I should use ext4 in sda7 instead of btrfs? This too seems too tricky. Why is there not visible install ubuntu alongside with windows, only erase disc or something else.

Here is installation type: install ubuntu alongside with windows. https://sites.google.com/site/easylinuxtipsproject/installation Why there is no this option when I try to install ubuntu?

[spacerocket]

maybe this is the solution: https://sites.google.com/site/easylinuxtipsproject/reserve-10

[spacerocket]

I installed ubuntu 13.10 with these settings but there is once again no ubuntu 13.10 on the bootloader, only windows 7! That`s very strange.

[spacerocket]

Creating a partition for /boot won`t change much I guess, I already tried that without success. The boot throws me always at windows loader whatever I do don`t know why.

[oldfred]

Did you use btrfs?

I am changing your title to include btrfs, as only a few have experimented with it and they may then see this thread and can help.

[spacerocket]

No I didn`t I followed very carefully the instructions from here: https://sites.google.com/site/easylinuxtipsproject/reserve-10

[oldfred]

Then post a new link to BootInfo report.

Post the link to the Create BootInfo report. Is part of Boot-Repair:
https://help.ubuntu.com/community/Boot-Info

[spacerocket]

Ok... so I should copy the new http:// paste .... link created and send to boot.repair@gmail.com?

[oldfred]

No, have not seen Yann around for ages.
Just post link.

Ok now I went again to recommended repair. Now the system told to write some commands to "lubuntu terminal window" and after writing them the terminal window told "no such command". Then it asked Remove GRUB2 from /boot/grub? It couldn`t go forward, I don`t know what happened.

1 disks with OS, 1 OS : 0 Linux, 0 MacOS, 1 Windows, 0 unknown type OS.

Now, I find that comment in the Boot Repair report very interesting. It means that Ubuntu is not installed. The Grub configuration files are in sda6

Boot files: /grub/grub.cfg

And Grub config is telling Grub to look here

set root='hd0,msdos6'

That is the first hard disk and the 6th partition = sda6 but is Ubuntu on sda6?

Grub uses a tool called os-prober to find the location of any OS including Linux kernels but when Boot Repair ran os-prober it got his back

os-prober/dev/sda1:Windows 7 (loader):Windows:chain

And that is all. When I run os-prober on my machine by running sudo update-grub I see this.


Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.13.0-21-generic
Found initrd image: /boot/initrd.img-3.13.0-21-generic
Found linux image: /boot/vmlinuz-3.13.0-20-generic
Found memtest86+ image: /boot/memtest86+.bin
Found Windows 8 (loader) on /dev/sda1


Boot Repair should be showing the Linux kernel and memtest in the OS-prober report if they were installed.

Regards.

Ok now I deleted all possible linux kernels and have Windows C 45,29Gt and Unallocated space 66,50Gt.

1) Maybe I could re-install windows and see if that fixes anything

2) Or you could tell me what partitions I should create when choosing something else from select installation type. Note: I have not the option of going for Install ubuntu alongside with windows.

Thanks for your time.

You may have other hidden data on drive.
Was system or drive every RAID, did you use gpt partitioning, did you create partitions with Windows and it converted to dynamic (not basic) partitioning.
Most of reasons for installer not showing Windows, any partition type error
http://www.rodsbooks.com/missing-parts/index.html

For manual partitioning you need the /(root) and swap.
I suggest / of 20 or 25GB, swap about 2GB, and if dual booting include a NTFS shared data partition. But you cannot create NTFS partition during install, so either partition in advance or leave space during install and use gparted. The remaining space would either be /home or /mnt/data partition formatted ext4. If less than 25GB just include that in / (root).
