Since installation of Ubuntu Precise I have problem with boot time: nearly 45-60 minutes. I have no idea what's wrong. My system is up to date. I have also boot chart installed but don't know to inter prate the logs. One example is here.

There also other logs from boot chart but I don't understand them. Regards and thank you for help

  • I'm not an expert on boot optimizations but this boot chart seems to be pretty normal looking for your computer's age (I'm guessing it's slightly dated since it's an Athlon dual-core). Also, there's a large period (between ~42-52 seconds) where the system doesn't look to be doing anything. Is that at the login screen? If yes... this really looks like a typical boot.

  • Also, it indicates that you're using 11.10, not 12.04...

  • Okay, people who keep putting it back to MINUTES instead of SECONDS: Look at the bootchart.

  • Hello and thank you all for the answers. The time of booting was changed by me becouse thats fit the true. Not 45seconds but 45minutes takes in best speed the booting time. If the bootchart log is okay thats mean simply that the problem is elswhere. The quastiuon is, where? Aha, I'am runing 12.04 64bit and not 11.10. The booting problem was from the beginning the issue. Before that I was using lucid linx which was booting perfectly. is there any possibility to find out whats wrong? Could that be some wrong Bios configuration?

  • If you could attach a bootchart that deals with your current system instead of an older one, please do attach it. What happens during boot? Is there a black screen for much of it? There might be something that needs user attention and it's not displaying it.

I really have to say that it's very likely that your filesystem has been damaged or the upgrade really hosed key system files. I would highly recommend backing up your files and reinstalling as when a system is in such a state it's usually too much hassle to pinpoint the problem.

To back up your files, you can download Ubuntu and use a LiveCD to mount your Ubuntu partition in the file manager. Navigate to /home// and your files will be there for the taking. Back them up to a thumb drive, wipe the computer and reinstall, then move the files back.

Another task that might be beneficial is to make sure that your hard drive is not failing. You can use Ubuntu's Disk Utility: Select your hard drive, then select "SMART data". Perform a short test and see if it tells you that the drive is about to fail (if it has a few bad sectors it's not worth fretting about as it's not uncommon).

  • Also, if you want to be very thorough (though it's not necessary to do if you don't want), before you start up the Ubuntu installer you can launch "gparted" through the dash. Select your hard drive after it boots, then select "Device>Create Partition table". Allow it to create a new MBR partition table (the default choice). Then install Ubuntu.

  • But what I dont understand is, that the boot sequence dosnt hang on Bios or system load sequence but BEFORE. Cold booting get so slow. When I do restart OS, the boot is absolutly normal. Thats mean also filesystem behave normal.I have also made disgnostics of my filesystem and mbr ...there are no errors. There are only physical problems with the soundcard which seams to be broken. I would say that the is the problem of the motherboard or powernet. But anyway...to backup the fules is always a good idea. Thank you

  • user43484, you may be right. You may very well have a corrupted BIOS. Did you flash it recently? If you're having other hardware problems it looks like it certainly may be a motherboard issue. You could also look for a BIOS update from your vendor.
