stuck in rebbot loop need help

using samsung chronus 7 laptop
windows 8.1 64 bit O/S.

Problem
On start up get the samsung screen then a blue screen with a sad face saying pc needs to restart. Then goes in a continus reboot.

tried using the w8 recovery cd. But get on the screen press any key to boot from cd. but press any key has no effect and goes back into loop as before.

press f2 to get to bios reset defaults, no luck either, tried f10 just get boot up order, unable to find what keys boots into recovery mode, f8 does nothing no safemode.

any one offer any help or advice please windows was pre installed.

Try booting from a Windows 8.1 disk (DVD/USB) not a Windows 8.

got a problem with cd's i put the cd in and the screen reads hit any key to continue to boot from cd but hitting any keys has no effect. [but the keys when in bios work ok]

all i can do is force power on off via power button and access bios via f2 and boot order via f10. I do not know what keys to hit for hidden partition factory reset/back up partition etc or safe mode.

You can use the OEM manufacturer's Recovery Disks to boot.

unable to get pc to read from the cd, screen says hit any button to continue but it just re loops again same with a dongle

Are you boot disk in UEFI mode?

thank you all for advice. now gone back to samsung for repair, they stated a 7 day return for warranty repair. big draw back will have hdd reset to factory settings during repair/testing.

needed new hdd also new m/b
