Dual boot with windows 8 - Not able to start kubuntu

[SteveRiley]

The rest are comments, aren't they?

Yeah, true. Anyway, the problem isn't here.


Continuing...here's the portion of your /boot/grub/grub.cfg that's supposed to allow you to boot Windows 8:

### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows 8 (loader) (a /dev/sda4)' --class windows --class os $menuentry_id_option 'osprober-chain-1E64807664805287' {
	insmod part_gpt
	insmod ntfs
	set root='hd0,gpt4'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt4 --hint-efi=hd0,gpt4 --hint-baremetal=ahci0,gpt4  1E64807664805287
	else
	  search --no-floppy --fs-uuid --set=root 1E64807664805287
	fi
	drivemap -s (hd0) ${root}
	chainloader +1
}
menuentry 'Windows Recovery Environment (loader) (a /dev/sda5)' --class windows --class os $menuentry_id_option 'osprober-chain-84F8D25EF8D24DD4' {
	insmod part_gpt
	insmod ntfs
	set root='hd0,gpt5'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt5 --hint-efi=hd0,gpt5 --hint-baremetal=ahci0,gpt5  84F8D25EF8D24DD4
	else
	  search --no-floppy --fs-uuid --set=root 84F8D25EF8D24DD4
	fi
	drivemap -s (hd0) ${root}
	chainloader +1
}
### END /etc/grub.d/30_os-prober ###

But it isn't working. I have an idea for a workaround.


And here's the mysterious "system setup"!

### BEGIN /etc/grub.d/30_uefi-firmware ###
menuentry 'System setup' $menuentry_id_option 'uefi-firmware' {
	fwsetup
}
### END /etc/grub.d/30_uefi-firmware ###

I've figured this out. Every UEFI-equipped machine includes a very basic boot manager, which displays installed operating systems that the UEFI knows about. GRUB is now providing a menu option to start the UEFI boot manager. Huh. Since I don't use GRUB, I hadn't realized it had gained this capability.


But we still need to fix your GRUB so that it boots Windows. Boot back into Kubuntu and open a console window. Then type:

sudo nano /etc/grub.d/40_custom

At the bottom of this file add:

menuentry "Windows 8 (alternate boot method)" {
  search --set=root --file /EFI/Microsoft/Boot/bootmgfw.efi
  chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}

Press Ctrl+X to save and exit.

Now type:

sudo update-grub

Reboot. In the GRUB menu, select Windows 8 (alternate boot method). Let me know if that works.

Eh, check this out! https://bugs.launchpad.net/ubuntu/+s...2/+bug/1024383

Sheesh. Confirmed, critical, yet unassigned. WTFF?

The bug report contains some interesting ways to fix the problem. Before we examine those, though, please try what I just suggested in the previous post.

[Monica]

I wasn't at home until now, couldn't try it earlier

Eh, check this out! https://bugs.launchpad.net/ubuntu/+s...2/+bug/1024383

Yessss, that's exactly that!

I tried what you said and it worked!!!!!!!!! So now what?

I'll try to read the forum thread in french and the bug report now too....

[Monica]

I was still puzzled why windows didn't find the partitions so I tried again and this time i found this:

that's too much for me.
i know it's silly but I'm kind of happy that it was a bug (yes, I know it makes no sense that it is
critical confirmed and unassigned)... it sort of means that I am not completelly hopeless.

[SteveRiley]

I was still puzzled why windows didn't find the partitions so I tried again and this time i found this:
{...link snipped...}

Windows now sees all your partitions, finally. I don't understand why it didn't earlier, but hey, let's not worry about that now

I tried what you said and it worked!!!!!!!!! So now what?

The last thing to do is format that large partition as NTFS and then set up Kubunto to see it. I'd prefer that you do the formatting in Windows. So please boot that, open Disk Management, right-click the 583,94 GB RAW partition, and format it as NTFS. Use "quick format," it's faster and the end result is the same.

Once that's done, please boot back into Kubuntu. Show me what's in /etc/fstab. I want to see what it looks like now, before we start adding stuff.

Also, just for good measure, show the output of

sudo gdisk -l /dev/sda

[Monica]

I didn't find the folder /etc/fstab, only /etc/fstab.d and it's empty.

I can access the data partition dades both with kubuntu and windows.

[SteveRiley]

I didn't find the folder /etc/fstab, only /etc/fstab.d and it's empty.

That's because /etc/fstab is a file. Yeah, I should have been clearer. When I say "let me see what's in foo, if foo is a subdirectory, you'd display the contents with ls -al foo. If foo is a file, you'd display the contents with cat foo.

sudo gdisk -l /dev/sda

Your partition table looks exactly like it should.

I can access the data partition dades both with kubuntu and windows.

Hey, I think everything's sorted now! For my own curiousity, I'd still like to see your fstab. So please show the output of

cat /etc/fstab

[Monica]

Oops, no, i should had found it, I was too excited to think, It finally works!!!!! That's really great, I don't know how to thank you...
I hate working with windows so much and I had never solved that alone. That's just another reason to love kubuntu, that there's people like you around..

[SteveRiley]

Hm, interesting. Your NTFS partition isn't getting mounted via fstab. Something else must be auto-mounting it for you. I don't run dual-boot, so I'm kind of figuring this stuff out as we go along.

What's the output of:

cat /proc/mounts

I'm glad we got everything sorted for you. Even though we're up to 39 posts on this thread, yours has been one of the cleaner UEFI dual-boot scenarios to get going correctly.

i don't understand any of it...

[SteveRiley]

Well, I understand what's in that output, but I don't understand why we can't seem to discover is exactly how Kubunutu is finding and mounting your NTFS partition! You said you can see it, that's cool. I presume you're using Dolphin to access it?

One more bit of investigation, if I may...what's the output of these two commands:

ls -al /mnt

ls -al /media

[Monica]

Yes, I'm using Dolphin. You can ask me to run so many commands as you want ;-), I'm not just disappearing because it's solved for me!

monica@antalya:~$ ls -al /mnt

lrwxrwxrwx  1 root   root     42 abr 15 21:41 .hidden -> /etc/kubuntu-default-settings/hidden-media

[SteveRiley]

Yeah, I suspect Dolphin is automatically mounting it for you, using a technology called FUSE, "File System in User Space." You can see this here:

monica@antalya:~$ [B]ls -al /media[/B]
total 12
drwxr-xr-x  3 root   root   4096 abr 19 20:42 .
drwxr-xr-x 25 root   root   4096 abr 15 22:02 ..

lrwxrwxrwx  1 root   root     42 abr 15 21:41 .hidden -> /etc/kubuntu-default-settings/hidden-media

Dolphin is automatically mounting it under /media for you.


Try this. Open Dolphin, then open a console window. Now show me the outputs of

cat /proc/mounts

udisks --enumerate

udisks --enumerate-device-files

Sorry to be using you as my lab rat

it's kind of fun. you're lucky you're so km away while otherwise I would be asking tons of questions ;-), I'm curious.

[SteveRiley]

Yep, it's a FUSE mount created by Dolphin. Notice that we can now see it in /proc/mounts:

/dev/sda9 /media/dades fuseblk rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096 0 0

The fuseblk type indicator is the clue.

I have personally never needed to check into this, since I'm not a fan of dual-booting. So hey -- we both learned some stuff here! Kewl :cool:
