First of all, apologies in advance I am a newbie. (I have used Linux for 2 years and use Arch Linux currently. I managed to installl gentoo last year on my thinkpad, so I have a teeny weeny bit of experience). So please bear with me!!

I have downloaded the minimal cd image several times from the main server which was incredibly slow took about an hour. I burnt the iso image on a brand new rewritable dvd, and tried to install it on three different laptops (Advent Tacto, Lenovo M30-70 core i3 laptops, these are all running arch linux for now). The problem is that although I successfully burnt the iso on the dvd, on bootup the dvd is not recognised. I dont know why this is happening. I have checked that the downloaded image was not corrupt, as specified in the handbook as the optional step. I also had the same issue last month and gave up. Last month, I tried mounting the image on a usb using the dd command in terminal, then tried unetbootin. ... etc. Well, it didnt work.

This morning I found the local mirror in Vienna, Austria and I burnt the iso image on the dvd again I am still facing the same issue. I am using an external dvd drive and it does work normallly.

In case this is relevant, I have legacy support enabled in the bios for the Lenovo laptops. Unfortunately, I cannot access the bios in the Advent laptop (thats ok because I am getting another laptop today HP Elitebook 2670p core ii5 with a digital pen).

I would be very grateful if you anyone would point me in the right direction. I am aware that I can use the Rescue CD option, but I really want to follow the instructions in the handbook and learn about gentoo.

Thank you in advance for any suggestions and your tolerance for newbies.

Your BIOS/EFI cant see gentoo bootable medium so you are not able to access bootloader menu? Am I right?

Thanks for your reply. I certainly can access the bootloader but I dont see the Gentoo USB or Gentoo CD via the plugin DVD drive. I have tried 3 different USB sticks, different mirrors, burning the DVD on both Arch and Windows, no joy.

I did not have problems with detecting Arch Linux USB disk via the bootloader.

The BIOS has Legacy options selected on two of the laptops. The first laptop currently has Arch Linux running only and it only has Legacy option enabled. The second laptop has dual boot Windows 10 (upgraded from Windows 7) and Arch Linux (again only Legacy is enabled here). Both Laptops are Lenovo M30-70, core i3, 4 gb ram, 64-bit.

The third laptop has a blank hard drive and unfortunately I cant access the BIOS (Advent Tacto), this one is going to be recycled so am not so bothered about it. It does detect whatever os (arch linux, linux mint, etc) is mounted on usb except for gentoo.

Should there be any issues installing gentoo on the laptops (64bit, have legacy support enabled)? Have I missed something!!


Many thanks for your help and time!!

1. You've named a BIOS boot menu as a bootloader. They aren't the same. :)
Bootloader is a program on the boolable mdium. It helps to load the kernel and mount filesystems.

2. I had met this problem. It seems that gentoo developers have cut some drivers from the bootable mediums.
Here is my post https://forums.gentoo.org/viewtopic-t-1027744-highlight-.html
Try to boot from these: install-amd64-minimal-20150625 (date is necessary) and systemrescuecd-x86-4.3.0
Also note! You can install gentoo from any Linux-like bootable medium as well as Arch Linux.
So you can just follow the Handbook with you Arch image. Enjoy your Gentoo after the chroot step. :)

I do know the difference between BIOS and boot loader. What I had tried to say was that the BIOS settings on my laptop had been configured to Legacy settings and it also had an option to see the prirority of the boot options. There is a separate button on the side of my laptop which takes me to a menu with the following items 1 BIOS setting )which also allow me to configure the Bootloader and security settings as sub menus), 2.Boot menu (boot loader this is separate), 3.Normal Setup 4. System Recovery etc..). I thought it was important to know whether I had Legacy option enabled or not, thats why I mentioned it. Perhaps I did not clarify this information.

Perhaps its not my day today. Many thanks for the hint, I will try it in a few days time. Thanks for your help and time.

Please if anyone has suggestions not involving SystemRescue route, I would be interested. I would like to do the installation as suggested in the handbook and without SystemRescue or using another Linux distro option. I wont give in and I should be able to do this myself.

Thanks for all your hlelp

The handbook suggest to use Nero or EasyCD creator to burn the image with Windows, but of course you have many other ways/programs to do that.

Until you reach chroot part, you are not following any gentoo doc to install gentoo, just a doc suggesting you ways to get to that chroot part.
If the handbook suggest something (disk partition tool to use, disk partition scheme, boot cd...), and you cannot use it or don't like it ; then use the one you can or the one you like.
So anyone would suggest what he likes, but what is important in the handbook start at #14 mounting, what is before is up to what you like.
All before this #14 chapter just cannot be followed ; if you follow the suggest to burn in linux with cdrecord then you're under linux and you cannot follow the suggest to burn with Windows...

Use what you like, it looks logic to use your arch usbkey as your computer see it, but if you don't want use it, fine, but sorry the handbook cannot cover any installation media trouble, and it doesn't cover if your minimal cd is not working, nor it would cover if your arch usbkey wasn't working...
People will most of the time suggest the SystemRecue cd, because they use it, and it has work for them, and they advise to do like they do ; but even following this advise cannot lead you to success, it works for many, but it sure fail for some too.

Find a way yourself to reach that part #14 state, if you have a trouble to reach it, find another way, or find yourself why you couldn't reach it (something that is most of time over any new user and sure over your "i should be able to do myself").
But asking us, why an hardware cannot boot this usbkey or livecd is like asking us if we knows all hardware and exception that exists to use them. Sorry we don't (and our bootcd can be buggy, unlike other distros, we never reinstall gentoo, the bootcd is only use by new users and so, not test by many, as most gentoo users use it one time only).

If you're lucky and a user with the same laptop is near and he has use the minimal cd, you'll get an answer.
If you're not lucky, better stop wasting time to find out why you cannot use it and use something that works and it could be whatever you like, as long as you can reach the #14 part.

Thanks for being honest and representing Gentoo's approach to not cover media installation issues in their handbook. That is off-putting and sad. Gentoo handbook actually does mention how to burn the image and how to create a live usb disk.

I suppose the general answer is that the failure for making a bootable usb disk and creating a DVD or CD image issues using numerous laptops (now amounting to 4), mirrors, operating systems is ALL MY FAULT. This is interesting, because I would like to know why I was able to do the gentoo installation last year without any problems with the live usb disk (again I had a 64bit thinkpad laptop). I will no longer be consulting this forum for any ideas, and I WILL NOT USE MY EXISTING ARCH DISK OR USE A SYSTEM RESCUE CD. I am not asking for being spoon-fed either, because I wanted to know why someone would encounter these issues in the first place!!!

Of course, I note the hostiliy towards newbies. However, I am sorry that Gentoo handbook and the related wiki are not going to help with clarifying why one encounters these issues during installation. Work-arounds are not really sustainable solutions.

Thank you Gentoo forum for all your VERY HONEST, encouraging and helpful replies. Of course I will never ever come back to this forum. Good luck and Thanks for everything.

If you ever comes back when your blood is getting back red and exit your Hulk phase ; generally everyone accept "i was drunk" as excuse for saying something stupid ; in case you need one.
And before linking this thread to other forum in anger like a proof that we are insane ; re-read it again, it might saved you from shame.
