Marco Braida answers a lot of questions on this matter at launchpad.net. --Question 120822. He seems to suggest the issue is related to Wubi, and urges installing on an actual partition. I am not sure where the problem lays, but somewhere in the combination of easy-to-use tools, I ran into some big trouble. If I was a Windows user "giving Linux a go", this would have been a poor beginning. :unsure:
Thanks to all who helped.
PS: NTSC is a television broadcast standard. I spent many years as a broadcast engineer. NTFS is a file system, and that is what I meant to have typed. And the Wubi install was pointed into a partition I created using the Windows Disk Manager MFC in empty space on the drive.
This is an excellent summary. I ran into just this issue, and on researching it here and elsewhere I found the things you say about Wubi to be the case. The Wubi install is very easy. It is silent. For the most part everything autocompletes. But yes, it, or something it contributes to, can cause a problem with booting the computer, in my case, after Ubuntu offered auto updates. This was un-recoverable, so I eventually just did an install from the iso image, as you suggest above, and told it to delete and use the entire disk.
My problems focused around booting. After powerup, when the computer was running through its list of PCI connections, this process terminated early, and it changed to "Boot From CD ROM:" If the CD was in the drive, it rolled the CD. If not, it returned a "No Device Found error, and terminated the boot. The last thing in the PCI device report was ACPI, and this line was not displayed completely. Many sources recommend adding "noapci" in the bootloader file. This may help, but as my computer would not boot, I found it hard to edit that line. Some skill with using a live CD to edit files in the install will be valuable, and I intend to learn them. On the other hand, Wubi may have modified the MBR of my Win7 install, and in that case some of my helpers have suggested that the answer is to run FIXMBR using the Windows rescue disk.
There seem to be a number of people who fall into this problem, and the traffic I have found focuses on ACPI, Wubi, Ubuntu 10.4, and, again, the upgrades that are offered after you are running, which was the beginning of my problem. If Cannonical intends 10.4 to exploit the gap caused by the release of Windows Vista, then it must not be this easy to blow up a working machine.
Thank you, All.
