I recently purchased a Japanese manufactured NEC LL750/J laptop while in Japan. Because the Windows 8 that came installed was somewhat in Japanese (even after you chose English there are many instances where something pops up in Japanese) and so I wanted to perform a clean install of Windows 8. I paid for and purchased Windows 8 Pro. I downloaded the iso file onto both a DVD as well as USB. I then set the BIOS to English and the boot order to CD/DVD first and then USB and then HDD. The NEC laptop just skips the disk and USB and starts Windows 8. I attempted to use a Windows 7 iso boot disc that know works fine and again it skips the disc and starts Windows 8. I was concidering purchasing Windows 8 OEM from the store and seeing if the OEM disc would work. But, I already feel burned bad enough having paid for Windows 8 Pro. I don't want to purchase Windows 8 Pro again only to find the problem lies somewhere with NEC BIOS settings. Any suggestions would be greatly appreciated, Michael Note: I have installed Windows 7 and downloaded software etc.. but I'm not that experienced with computer BIOS other than to set the boot order.
Set the BIOS to default settings , then change the boot order to boot from DVD ,see if this works .
Just make sure ISO files or DVD you are using to boot with are actually bootable disc for OS ,as for USB booting ,you will need to turn on usb boot on the bios and software needs to be USB software.
and I am not talking about boot order that you have already selected.
check windows 8 software on anther machine and see if you can boot with it
I checked the Windows 8 Pro iso disc on another machine and it did begin the boot process (ie: 'press any key to continue...' after which the Windows 8 logo was displayed and eventually it started the installation process at which point I stopped and took the disc out). So it seems like the iso DVD is fine. There seems to be something going on with the NEC not reading the disc? Even when I put a Windows 7 Pro recovery iso disc into the NEC laptop it bypasses the option to boot off the disk and loads the Windows 8 installed OS. Any ideas?

enable the option to check other boot devices, it should be the next option after the third boot device, also select the first device as USB DVD/CD

you may have to check the registry manually and if this will not work, you may have to reinstall windows.
1. click start > run > regedit > ok.
2. In Registry Editor, expand the following registry path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class
3. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
4. Delete Upper and Lower Filters. (If only one is availabel, that's fine).
5. Restart system and check your drive again.
NOTE: Make sure to do this correctly or else, system will not load to windows.
If manually deleting upper and lower filters will not work then you may have to backup your files and reinstall windows.
SOURCE: my laptop won't boot from cd
if u can boot from CD rom without ur HD then ur booting is OK. BIOS has nothing to do with ur HD booting.....it's just that the machine starts from BIOS 1st...then looks for the HDD to load the Win boot files..else it goes to CD rom for the boot files...and so on...
check that the boot from HDD sequence is not disabled in BIOS.
keep this boot seq
1 CD ROM
2 Floppy
3 HDD
4 USB HD
try this...1st
disable all 1 to 3 in above seq
connect a USB cd rom drive or a USB pen drive
ensure that ur Win disk is either in the USB CD rom drive or Win install files(copy of Win CD) are in a USB pen drive check if it boots from the pen drive....
after you boot....
connect your HDD now check if it can recognise the HD....else we can work on plan B
