Ubuntu 8.04 startup problems


I run a cnc machine using Ubuntu 8.04 and have two startup problems.
1. Every time I start the computer, I get the screan saying "Starting,pleast wait" then it goes to a blank screen. I have to shut off the computer and start it again. Then I get the Loading screen with the progress bar going left to right with the OS booting corectly. Every time I have to start it twice.

2. When I get the progress bar loading the OS, it wants to do a harddisk scan and allwas fails if I don't use the Esc key. How can I get it to stop doing that scan. I only use this computer to run EMC2. Any help? Thanks Carl

The fact that the hard disk scan always fails would indicate that there's something wrong with the hard disk. Until you can make that problem go away, all bets are off. I think that problem would be the first one that I'd tackle.

I would recommend booting to a Live CD of something (Knoppix would be one good choice) and scanning the hard disk from the Live CD, making note of any errors reported.

Also, Ubuntu 8.04 is way old in Ubuntu terms.

Thanks, Frankbell. I will give knopper a try. This Ubuntu 8.04 is only used to run EMC2 on my CNC router. While starting twice and hiting the Esc key alwas works it is anoying. Thanks again Carl

another piece of advice, if you can access your files from the live cd, make sure to copy them somewhere onto a drive that isn't dying, such as a thumb drive or external hard drive, that way if the hard drive DOES finally conk out, you don't lose your files.

not everybody gets a chance to back up their files after they start seeing symptoms of hard disk failure, so if you can copy your files, count your lucky stars you can and do so.

Can I do a disk scan from within ubuntu? This does start and run ok after double startup.
This is duel boot with XP. Will a disk scan from windows help?

The only files I have on this computer are nc. files for the CNC and I can put all them on a memory stick. That will be no problem.

You can direct Ubuntu (or any Linux) to a disk scan upon reboot before mounting the drive.
