<pre>Hello, I had the same problem even with 9.04 and in my case i found a tricky solution. I have a motherboard with a fakeRAID soution based on an intel ICH10 but i prefer to use the software RAID that come to linux. The problem is that the dm_raid45 module necesary to use fakeRAID that i "don't" activate during installation is really activate and in some manner blocks the linux software raid. The solution in my case was easy when i got to find the problem :) - Boot from other media (i used the ubuntu alternative install cd) - Mount the root, the boot and proc partitions - chroot to the installed ubuntu - apt-get remove dmraid In the process it re-make the initrd boot image without the tools and modules of the dmraid and after rebooting it boots perfectly. Hope it helps you. Mario | Hi @ll, | | I hope this is the correct platform to discuss my problem, otherwise please point me in the right direction. | | I installed Ubuntu 9.10 (being new to Ubuntu, but not to Linux in general). After finishing the installation (from an USB pen drive), the | installer told me to reboot. But the system hangs on boot with merely a blinking cursor on the screen, no loader messages (I chose grub2 as | boot loader), nothing. | | Since the mainboard does not feature IDE ports and my SATA hdds seem not to be willing to boot, I am only able to use USB pendrive for | diagnostic purposes, for instance the Super Grub Disk. However, I did not succeed to find any useful information to my problem. | | Could somebody give me a hint what I can do to either solve the problem or at least diagnose it in more depth? | | | Some facts: | During Ubunut installation, I configured a software RAID: | My 3 HDDs are partitioned having a 4 GB and a 1,5 TB partition each. | Two of the 3 4 GB partitions are used a RAID1 system disk (root filesystem), the 3rd as a Swap Area. | The remaining three 1,5 TB partitions will then be used as RAID5 but this is a second issue. | | Once again: | hda1 ... 4 GB added to RAID device #0 (RAID1) | hda2 ... 1,6 TB added to RAID device #1 (RAID5) | hdb1 ... 4 GB added to RAID device #0 (RAID1) | hdb2 ... 1,6 TB added to RAID device #1 (RAID5) | hdc1 ... 4 GB added to RAID device #0 (RAID1) | hdc2 ... 1,6 TB added to RAID device #1 (RAID5) | RAID device #0 ... ext4, mounted at / | RAID device #1 ... ext4, mounted at /data | | The BIOS boot sequence is: only from HDD (I disabled booting from removable media or CD-ROM). | | | Thanx a lot in advance, | Andi </pre>
