....[ ]....At this point, he should download the manual on his system from the manufacturer and read about how his system is supposed to work. He may not know if he wants/needs bootable media (CD or USB) to restore old system or to install new.
To recap. Ubuntu doesn't give a flying snot what you try to install it on, it installs. On a pre-built system done the way it's supposed to be done, you have restore discs. These are images of the OS and app installation discs. A locked BIOS (?) precludes you from installing from a Windows disc, but rather the "restore discs" with which it came.
In any case, I've had 10 years of stories, fables, and lore, about how people needed to crack the BIOS password in their Dell laptop, because the dog ate their restore discs, etc. Mercifully, I never learned how, and everybody else here that did know, was informed to "cease and desist".
Ubuntu not allowing someone to download another OS is a crock of sh!t. In fact, Ubuntu, (or other Linux distro), is usually the first line of defense against non booting Windows installations. You can run it off a CD, a USB stick, and reclaim all your files before you wipe a Windows installation. And, it will go online with FF, from a "live" (uninstalled) run.
As far as boot order goes, there's a button for that. In fact, that's something I should do the next time I start each and every one of my computers,
write down that damned button's name! Not only that, the boot menu attaches to BIOS, not to Windows.
Now, if a Linux distro has been installed, GRUB makes it the first OS to boot, and you need to use the keyboard to get into Windows. The only "no access" message you'll get, is if you set a "root" password, and forgot it
.
And I'm pretty darned sure
, a live run doesn't either ask for, or allow a password.
