Ubuntu 7.10 beta wont install

Does the system freeze, or is it just that the graphics don't work? Some hardware specifications would also be handy. I presume that you have given it enough time.

The system does freeze, and nothing happen while I wait.
I have Pentium D processor and Nvidia gforce 7100, Flatron L1753S monitor
80GB harddisk, all 4 months old.

If I can compare Boot-time for Feisty CD and Gutsy then certainly something is wrong with the beta Gutsy CD.

maybe try to remove some boot options (e.g. "splash" and "quiet" ) from the kernel options to see where the live cd hangs...

How do I do that?

And where to fix kernel options in the cd?

there is an option (F6 or something) in the live cd boot menu to change boot parameters ...

Try the safe mode first, you could also try the alternate cd if this one gives you problems (alternate has just text installer, so it's not so good if you just want to try).

To edit boot options instead of clicking "start and install", you press F6, then 'e' to edit boot options, then you select the kernel line (longest) and press 'e' again. Now you can remove "quite" & "splash", or try adding some things for example "noapic" or "irqpoll".

The same happens with feisty and gutsy cds, or it's just gutsy?

Thank you. The only cd hat wont boot and install is the Gutsy beta.
On the other hand Feisty boot and install well, but there I have big problems with what I think is my graphic card. Nvidia gforce 7100. And I am forced to use low-resolution and whats more important programs like supertu and Gyachi dont work at all.
I am back to Dapper at present time, and I give it a new try october the 18th.
If it still dont function, I must consider finding another distrubution that dont mess my HW.
Btw, none of the Ubuntu distributions I have used has been able to utilize CD-RW. There is a symbol CD-RW but it turns out it can only be written once, and from there only read access.

I was higly impressed with Ubuntu when this machine was brand new, (April this year) and I installed Ubuntu Feisty for the first time. But then after a while the Video-CDs I made was unusable. Rastersoft had a fix, but it didnt function here.
So after long time trying to fix Feisty, I am back to Dapper. And I cant understand why this "old" Ubuntu is giving me a much better result than the newer one. What is an update/upgrade from Ubuntu really? Dont they test what functioned well in the old version still can be used in the new?
I have been working as a computer system programmer/maintainer for 20 years, and these things are absolute basics for any serious computer program. My platform then was IBM mainframe and mostly Cobol.

Some comments:

The live CD is pretty slow, you might give it a longer time to start than previous versions. Let it go as long as it sounds like something is happening or if the drive light blinks. I seem to remember wondering if it was working the first time I tried it, and eventually it started up.

Some new CD drives are in need of a firmware update to work properly. Check the website of the manufacturer for an update.

Thank you. But the Gutsy beta is not bootnig beyond the start-up screen.
I tried some options in the start-up script as mentioned above. It give me a boot: prompt and after pressing enter I get msg Invalid kernel. How is that possible from a cd that has correct md5sum?
And I have waited like 30min to give the live-cd time to start, but nothing

You say that the CD has the correct md5sum. Is this because you ran md5sum on the .iso, or did you somehow run a md5sum on the CD itself?
Did you try the "verify CD" function of the live CD? It sounds like it got to the menu with that option, right?

I run md5sum from the cd-directory, /media/cdrom0 even I cant remember now how I did it. But the md5sum was correct. As far I can remember 'ff ' something.
I will give another try for checking the cd.

why not upgrade from 7.04 to 7.10 like i did.everything works great.this is the best ubuntu version to date.

Can you try with the alternate cd?

I did erase the entire HD with gconf boot CD, installed Ubuntu Feisty and tried to install Gutsy from there. But same result. Right now I download that Gutsy beta again, and will md5sum the iso when its complete.
Anyhow I am sure this is what I already did, and the cd is for one reason or another unusable.
This download just to make sure i'm not

...making any mistakes or saying wrong info

Please don't ask for gutsy support here, it is not released yet and as such will contain many bugs. If you find a bug (like you seem to have done), you are better to file it on the gutsy bug database.

Ok, here we go again... The md5sum from iso is ffe55d31659828a5bfbdb0ec2ee78eb0 and thats correct.

please also check that the cd was burned correctly by using the according option from the live cd boot menu...

How to check the cd when I dont boot? I am waiting while upgrade my Feisty to Gutsy, and it seems it might take long time.

I am upgrading from Feisty to Gutsy now, and will try to make a new cd after the 18th Oct.
