Hey guys, I'm having a problem with my netbook. How do you boot into a CD-ROM or USB? My netbook is a Samsung NP-N100S-E01PH. I could boot to a CD when I installed WIndows 7 but it could not detect Ubuntu CD Installer. Please help me any way possible.

If Windows setup boots but your Ubuntu media does not, the most common culprit is how the installer was created. For an external USB CD/DVD drive, make sure you burned the ISO as an image (not as a data disc) and finalized the disc. An easier and more reliable path on this netbook is a USB flash drive created from the ISO and verified by checksum first. You can verify the SHA256 from Ubuntu’s release page, then write the image with a tool that does raw, bit-for-bit writes (Rufus on Windows in DD mode, or dd on Linux). The official walkthrough is at Create a bootable USB stick on Windows and How to verify your Ubuntu download.

On some Samsung netbooks the boot menu lists the stick as USB HDD rather than USB CD; try every USB boot option and different USB ports, with other USB devices unplugged. If you reach the Ubuntu boot screen but then get a black display, edit the boot entry and add the kernel parameter nomodeset (press e in GRUB, append to the linux line) to work around Atom-era graphics quirks. Also confirm you are using an image your CPU supports; many older Atom netbooks need a 32-bit (i386) Ubuntu flavor.

Example (Linux) to write the ISO to a USB stick:

sudo dd if=ubuntu.iso of=/dev/sdX bs=4M status=progress conv=fsync

Replace /dev/sdX with your USB device. This erases the target drive.

Do you mean it won't boot from the CD/DVD/USB drive? Or does it try, but fail? If it tries, but fails, then you may have a bad image. If it won't try to boot from the device at all, then you probably need to go into the BIOS and tell it to boot from CD or USB. I have to do this with my work Lenovo laptop, as well as my Dell D630 personal laptop.

You have to ensure that the BIOS IDs configuered appropriately. Check the boot order/priority.

You can boot your computer very much easily by CD/DVD drive. But before start booting you need to configure your bios setup. Actually you need to set your primary boot media to your cd-drive or dvd-drive and also set the secondary boot media to your hard-drive. And also the Operating system disk must be bootable disk for proper booting. Other-wise problem occurs.

yeh, on bootup start pressing f11 or f12 as soon as the computer starts, should bring up your boot options without going into bios, choose cd/dvd and it should at least try to boot from disc, hope this helps. ps: if you can hit the pause button at the right time it should freeze the screen and allow you to read which button to hit, then carry on.
