Problem after successful installation with Boot (11.2 64)

Hello Community

I tried quit a few times to install 11.2 (64bit). It seems to me, as I have a problem when I configure within the bios the 2 harddisks as raid (doesn’t matter if raid0 or raid1)

The installations runs smooth without error. It boots also the first time correctly (after installation).

After a reboot I got the error message: “No boot deivce found”

It looks to me like I have a problem with GRUP. The disks are formated as ext4.

When I configure the harddisk as normal (without any raid) and do a reinstall of 11.2 the systems runs fine and I can reboot without problems.

Did anybody of you have a similar problem? I’m out of ideas atm.

Motherboard: Asus P5Q

Thanks in advance for any help

Tell us what is on each disc

If you have a live cd or something like Parted Magic, boot it and get us the result of this:

fdisk -l

At the moment I use no raid configuration. This way I can boot. The partitions are:

I’ll need to download first a tool and I will do a reinstall with raid. I’ll post the output of fdisk asap.

Thanks in advance.

Do you need raid. ?

Strange that you have decided to put everything on logical partitions.

As it is sda has the boot flag and I take it - it is the first HD in the BIOS boot order.

Let us know how we can help/

There is the output of fdisk after reinstalling 11.2 with raid0

If I need raid? Not really, but you know, you have it - so you like to use it :wink:

Regarding the partitions, I just took the suggestions of the installers. I’m not very fit in linux partitions. I’m not sure how to define the drives.

I just recognised, that no partition has a boot flag. I’ll hope I find a way to set one.

Ill keep u up 2 date.

Thx again :wink:

*Edit:
Yesterday I also installed 11.1 This worked well.

I tried with fdisk to set the bootable options. As far as I could see - it’s the device /dm-2 which I have to mark as boot. But unfortunality without success.

linux-5058:/dev # fdisk /dev/dm-2
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x400bd1b4.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help): a
Partition number (1-4): 1
Warning: partition 1 has empty type

Command (m for help): q

In this example you see the boot flag is on the extended partition. Which is OK, so long as you have grub set right. Typically I would not have the whole drive as an extended partition. And I would have the boot flag on the root partition with grub to the MBR.

Finally I get it working; I just did the partitions by myself and didn’t accepted the suggestion of the installation tool.

Thanks for your help; you brought me to the right way :wink:

This is good news:)
