[gentoo-user] booting from a usb flash drive
I believe I correctly dd'ed a minimal cd onto a usb flash (aka thumb) drive. I set the boot order on my new system (dell 7450) to have the usb storage device first. Sure enough I get the isolinux prompt and the kernel is loaded. However after asking for the keymap (I just hit enter) it types looking for the cdrom. There is no cdrom. It then tries to mount media /dev/sda[123] (which are dell and windows partitions). When this fails it announces no bootable medium found I tried adding the doscsi option, no change. What did I do wrong? thanks in advance, allan PS I did buy an external usb cdrom player and can dd the minimal cd to a blank media. However, I thought that I can install linux from a usb stick without a CD at all.

It works just fine if you use unetbootin to do the magic though. Is the partition table valid after you used dd to copy it over? If it isn't, try mounting the livecd. You might find a boot.img or something. This will vary though depending on the ISO you find. I ran into this with Crucial's boot disk for flashing (isolinux). I did dd bs=4M if=blah.iso of=/dev/sd? mount /dev/sd? /mnt/gentoo cp /mnt/gentoo/boot/boot.img ~/ umount /mnt/gentoo dd bs=4m if=~/boot.img of=/dev/sd? You'll have to update the device file accordingly. After I wrote the boot.img found within the ISO I was using, I was able to boot from the USB. Your mileage may vary. Sometimes dd works, sometimes it needs extra steps. Dan

Why do you want to use the gentoo minimal CD? if your laptop has EFI I don't think you will be able to configure it properly. (I'm not aware if the minimal cd has an EFI boot partition, but by the way you describe your boot it seemes it doesn't, is this right? you can check the iso with fdisk -l ) Either way I still don't know why the manual keeps recomending using a minimal installation cd for amd64 platforms, especially desktop types. I recommend you to boot somthing that has X, a browser and Networkmanager, I see no point the unnecessary pain of installing gentoo with a console only CD on such newer hardware. It's just complicating your life because you want to.

Alec I've only ever had two kinds of problem with unetbootin: Not waiting long enough for the write to complete. This is real easy when using corporate-gift-keyring type USB sticks (the thin ones without a USB-A casing around the connectors and no activity light Writing to one particular SanDisk product with a fancy Windows specific magic-sauce-protect-firmware, this stick does not boot no matter what I write it with. So as long as 1 use my eyeballs and keep my thinking cap on, unetbootin works OK for me. A reliable dd that always works would be first prize though -- Alan McKinnon alan.mckin...@gmail.com

If the first one doesn't work, by the domain you use(Meaning your Internet connection speed) I guess you could have been trying another image in ~10min.

Is not about fanciness, Is abut having the tools you need for the job, I understand you would choose a minimal if you were to try to boot an old celeron with less than 1gb of ram that would take forever to boot a modern livecd, but that is not your case, and the minimal and a 'fancy' have the tools my point is about being practical. BTW, I think if you had chosen the bulky live-dvd of gentoo it would have worked as expected.
