Hi, I am not new to gentoo, but new in this computer. I mean, I had an old pc with my gentoo installed and maintained over 6 years, now with the new pc I installed Windows 7 first and after, that, and cause I dont have cd/dvd device, I tried to install from usb, with no success.

I downloaded and correctly set up my usb drive (checked in another computer) but in my computer, even with USB-FDD selected in BIOS to be the first boot device, I have no success, but it is not an usb problem, cause I installed that way Windows 7 a day before, the only thing different from when I installed Windows is that the hard disk has 2 partitions, the default Windows 7 method, but I dont think that this could be the problem.

By the way, I am trying with system rescue cd, anyways, it does not matter until I can boot :?

Thanks in advance for your time and sorry if I made grammar mistakes, not my first language ;)

Pd Just if it is of help I have a GA 970A-DS3 motherboard, and my old disk with gentoo is around, but I have a multicore processor now (monocore before but both are 64bits) and new graphic card (but nvidia like the old one) just in case I can make use of it for something.

You may still be able to use your old gentoo installation. You'll have to chroot into it and reconfigure the kernel for your new hardware first, and then emerge -e world with appropriate cflags for your new cpu....

If all else fails you could at least use that to boot up so you can install on your new drive.

EDIT: Is this the same problem that you are having? http://forums.gentoo.org/viewtopic-t-938278.html

Uhm, I think that not the same problem, I use System Rescue CD and I can boot perfectly in a laptop, in this computer, the thing is not that there is an error, there is nothing, nothing more than windows booting, and is not funny to wait for install my distro and then see the windows logo.

I will try perhaps with the old this, I will plug it into another sata channel an see if it boots, I thought the chroot is made from the install medium, I will read on it, I only remember it from the time I installed with the minimal CD a lot years ago.


Bye and thanks ;)

I forgot to mention that I dont want to use the old disk anymore, I would like to install it on the new one, fresh install or cloning the old installation somehow.

Have you updated BIOS as recommended if using an FX processor?

Thanks, I used USB-FDD as it worked for the usb which I used to install Windows, I have not CDROM device, not sure about that option in boot option.

About update of the Bios I am using a Phenom x4, but I will check that.

I will edit if USB-CDROM works, but it would be weird since with USB-FDD worked before.


Bye and thanks ;)

EDIT It didn't work, it keeps booting windows, and is set in NON EFI.

So- you are actually using sysresccd on a flash drive? If so it may appear as a hard drive in bios. Suggest cycle through all choices and sub choices (if any) looking for your usb device, whatever it is. Also check that the bootable flag is set on it.

Zagloj,

It must be USB-HDD then. Most bootable USB sticks look like a partitioned HDD

Thanks very much, it works!! now in the Sysreccd the Xorg looks terrible but I am writing from here, now I can install from here like it was the minimal cd right? And as I have 2 partitions created I think I can create a third extended and then logical for all the gentoo partitions, as the handbook but logical instead primary.

Thanks again for all the help, by the way, I tried it with the gentoo usb but with not success, it didnt boot windows, only said Boot error, not vey much informative, but it is the same. An oh my god I must fix this screen flickering ;)

your boot partition needs to be primary. but /, /home, /etc can be logical.

More correctly, if your BIOS cannot read the entire HDD, your /boot partition must be physically located where the BISO can read the space it occupies.
When this was common, /boot was normally created first at the front of the drive, so it became a primary partition. However, its not required.
There has been a race between like this between BIOS vendors and HDD vendors since hard drives reached 32 Megabytes.

With 48bit Logical Block Addressing, the next crunch comes when drives reach 2^48 sectors, which is years away yet.
