When Windows xp is installed with a dual-system ubuntu, the Ubuntu Installation option is displayed at startup. The following text is displayed:
(Initramfs)/scripts/casper-premount/2-iso_scan: line 46 can't open/dev/sr0: No Medium found
Cocould not find the ISO/ubuntu-10.04-dvd-i386.iso This cocould also happen if the file system is not clean because of an operating system crash, an interrupted boot process, an improper shutdown, or unplugging of a removable device without first unmounting or ejecting it. to fix this, simply reboot into windows, let it fully start, log in run 'chkdsk/R', then gracefully shut down and reboot back into windows. after this you shoshould be able to reboot again and resume the installation.

Copy grub4dos-0.4.4, grldr, grldr.mbr, and grub.exe to the c drive, copy the isocopy to the c drive, then copy the vmlinuzand initrd.gz in the C drive, and then create the C drive.

After that, restart the system to enter the installation interface, but reveal the above error message. What should I do?
Some people on the Internet say they cannot put ISO on the system disk, but the tutorial can do it again. I don't know why. Please help me. Thank you !!
