Re: [Lubuntu-desktop] Boot problems with Natty Alpha ISOs
Hello everyone. Natty Alpha3 boots normally on the box in question, so I guess the problem was caused by some unidentified minor flaw in the build process for alphas 12, silently corrected by the new automated build process for alpha-20110228 and alpha3. Aftermath: - the CD with all the four alphas (1, 2, 3 and 20110228) are perfectly readable on both my main machine (the one where the discs were burned) and test box. dd if=/dev/cdrom.|md5sum results are as expected *on both systems*. - the main machine boots normally from all the four CDs - the test box rejects alphas 12 (BIOS does not recognize them as bootable) but boots normally from the other two alphas. Thank you all for help. Sincerely, Mikhail Maksimov On Fri, Mar 4, 2011 at 9:08 PM, Mikhail Maksimov mcwil...@gmail.com wrote: Hi, all. I've got a Pentium-IV box to test Lubuntu on.

Thank you all for help. Glad to see you are now up and running. It would be nice to know what caused the problem but, I doubt we'll ever know such are the vagaries for computers, and not just with Linux. I now have a machine that doesn't recognise Windows 98 XP boot disks but boots with any Linux distro I throw at it. -- Steve Cook (Yorvyk) http://lubuntu.net ___ Mailing list: https://launchpad.net/~lubuntu-desktop Post to : lubuntu-desktop@lists.launchpad.net Unsubscribe : https://launchpad.net/~lubuntu-desktop More help : https://help.launchpad.net/ListHelp

If you can't boot from a CD, it is difficult to get to the menu on the CD to use the test item there :) :) You *can* manually check the md5sum of the ISO itself, since we provide those both on the relevant Lubuntu Wiki page and as a lubuntu-whatever.iso.md5 file which can be downloaded. You can also check the md5sum of what you burned to a CD-R manually, but you need the number of 2K blocks the .iso file takes up to do that, so you need to do something like dd if=/dev/cdrom bs=2k count=$(($(stat --printf %s lubuntu-natty-alpha3.iso)/2048)) 2/dev/null |md5sum and compare the output with the md5 hash value in the lubuntu-natty-alpha3.iso.md5 file. The above is a decent test to do right after burning a CD. Once you are past that stage, and assuming you have multiple PCs around, I think it is probably easier (and may even be a better test of a CD) to just boot the questionable CD in a different PC, and run the Test CD menu item there, instead.

[Lubuntu-desktop] Boot problems with Natty Alpha ISOs

(1) Can you boot from your Lubuntu Natty Alpha CDs on a different machine? Just as a test that the CDs reall are bootable. (2) If the machine concerned has a floppy drive, consider using Smart Boot Manager to do an El Torito boot from a floppy (which then loads the CD). I would be interested to know whether this works. See http://btmgr.sourceforge.net for more about Smart Boot Manager. (3) Do please try the very newest Lubuntu Natty 11.04 Alpha 3 CD, which was announced today. I am not just saying this because I created it :) I used a more automated ISO creation process than was used for the other two CDs, so something *might* have changed that could help your machine to boot from Alpha 3, especially since my earlier alpha-20110228 ISO worked for you.
