hi i own a toshiba netbook nb250-107 and have found my self unable to install any dist of linux or win all i can instal on it are dist of win 7 witch i do not like … how can i solve this problem because when i try to boot any other dist beside win7 i get that little line in the upper left corner of my black color screen and it stays like that 4 ever and does not ask me if i want to boot from the device (usb) or not… is there anything that can be done ??? thanx.
Hi back02, and welcome to the forum 
How are you trying to install Linux ? … from a LliveUSB stick ?
Which Linux distribution are you trying to install ?
Which application did you use to create the LiveUSB stick ?
my only option is from a live usb
the images are mounted on the usb with poweriso and it is the same that i used to reinstall my win 7 ,
dist of linux tried : meego-netbook-ia32-1.20 and several others that i do not remember right now
I don’t think just using PowerISO to copy the contents of the ISO image to a USB stick is going to work, as it won’t be installing the bootloader, or making some necessary modifications to the LiveCD ISO for use with a USB stick … from a Windows PC, try using Universal USB Installer … from Pendrivelinux:
to create the LiveUSB from the ISO image (or one of the other LiveUSB creation utilities linked to from the PeppermintOS tutorial below)
There is a tutorial for installing PeppermintOS Two on an Acer Aspire One netbook here:
http://linuxforums.org.uk/index.php?topic=9782.msg70071#msg70071
which includes instructions on how to create a LiveUSB.
Obviously don’t do the stuff that’s Aspire One specific … but the instructions should work equally well on your Toshiba
BTW, I’d recommend PeppermintOS Two as an ideal Linux distro for a netbook … though you do have to tweak it a bit after installation … it’s all in the tutorial linked above.
Any problems, just ask
