I am trying to install ubuntu on an older tower PC I have from USB, Its horrible slow, I can bear with the waiting at the boot screen for 5 minutes but when I get into the install menus it takes for ever to get to the next page of the install process, I've left my computer on all night and I work up the next morning and it was finally on the next page. However I tried to get to the next page of install and it was back to waiting for hours.

My linux key is made with unetbootin on a linux machine, so I am trying to boot with the tag

acpi=noirq but it isn't helping I am still at the splash screen for...going on 5 minutes now. now I'm not even sure if I entered the tag in properly, It says hit tab to edit options and I just typed the tag in a pressed enter.

Strange. Can you provide some technical details about your system? – Jo-Erlend Schinstad Oct 12 '11 at 16:25
Also, if you can try from a more up to date image than beta2 that would be great. – Jorge Castro Oct 12 '11 at 17:04

If your old tower is late Pentium III, AMD Geode GX3 or very early Pentium IV, it is very likely that your USB is 1.1 only. Your best bet is to create a minimal USB image with debootstrap and chroot on another PC, then boot the old tower from that, repeating the manual command line install and partitioning. Putting in an old IDE-CDROM and booting from the netinstall CD may still yield faster results, though.

the tower I am using is an AMD Athlon 3700+ 768mb RAM a 7600GT etc etc so its all USB 2.0. I used the the same USB with the same distro on this laptop I am currently that uses a C2D and 3GB RAM. I may just break and burn it to a DVD seeing that its a CD Image unless now that 11.10 is out its in CD Size. Maybe it's the ISO itself and I can download the new 11.10 ISO and it'll work, I'll have to try it again when I have more time, Thank you – leveliv Oct 14 '11 at 4:31

The speed depends on the pen drive and the version of the port you are connection the pen drive to. If both are USB 2.0 or 3.0 the speed should be good, if any of them is 1.0 or 1.1... well, let's just say, you should go watch a movie and come back tomorrow.

For the speed of each version of the USB, there is the theoretical speed (Which I call the not true speed) and the other speed which let's call it the "Real speed you actually see when reading/writing something to and from the pen drive"

USB 1.0 - 192 KiB/Sec Theoretical (Real one was less than 100KiB/Sec)

USB 1.1 - 1.5 MiB/Sec Theoretical (Real one was less than 400KiB/Sec)

USB 2.0 - 60 MiB/Sec Theoretical (Real one was less than 40MiB/Sec. Tipically between 8MiB for a horrible 2.0 pen drive and 35 for a very good pen drive)

USB 3.0 - 625 MiB/Sec Theoretical (Real one is around 100MiB/Sec. At least for 3 pen drives I have tested. But this is because the max bandwidth from the usb 3.0 to the hard drive was bottlenecked by the hard drive lol. So the pen drive was faster than my hard drive. At least 100 a second is a very good speed.)
