There is two possiblities, first is boot sequence problem from your bios setup and second is your boot.sys file has been corrupted and in this can if you professional use console and recover it otherwise reinstall your operating system.

Ma laptop samsung rv510 froze while on internet last nite no buttons or anything would work including on\off button so took battery out and turned bk on now it wont boot up keeps coming up wae black screen...

It sounds like a hard drive failure. Try to test the hard drive in a desktop system to see if the data can be read. If so, copy everything you want and attempt to run a diagnostic to evaluate the derive. You likely will only get one chance to recover the data, so be sure you do it quickly.
Start here to find a tool to test the drive in another system AFTER you have tried to recover any useful data ( pictures, music, documents, etc)

Good day my sumsung R519/SA20/E251 problem it can open well but the problem it show blue screen and cursor what is might be a proble

From your description you have the the blue screen of death caused by a bad device driver, or corrupted windows, and possibly hard drive issues. If you have a recovery disc I would recommend a fresh install, if that is not an option I suggest a computer technician to assess the situation.

My laptop says boot from ahci cd-rom operating system not found and i have no disk but i can switch it on and press f2 which brings me 2 the set up utility but then i dont know what 2 do

restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

you could select the option start at last known configuration that worked this will tell you if and what file has been corrupted or missing then you will know if its a hardware issue then select restart if the problem still persists f8 back into safe mode you might need to select your operating system to load into safe mode

click start control panel administration tools computer management in the left panel events + to expand then system you will see all errors in right panel right click select properties this will tell you what has occurred and the time it occurred

you might use the system restore to restore your system to an earlier time click start all programs accessories system tools you should see your system restore option if it is a hardware issue the system restore might not work
if you need more help with this or if I have misunderstood the problem post a reply
hope this helps you

My samsung R519 laptop is saying boot from AHCI CD-ROM operating system not found. pls help

Windows has been completely corrupted, the only thing left to do is to reinstall it.
For that press F9 while the Samsung logo is on the screen and then select the Restore option.

Dropped laptop today, switched it on and it starts up, but comes up with black screen with following message: Boot from AHCI CD Rom: operating system not found But before that screen comes up...

It sounds like you might have damaged your HDD when you dropped it. It's saying that the operating system isn't found, and it's trying to boot from your CD ROM. Either that or you might have left a disk in the CD drive, I'm guessing that is unlikely but worth checking maybe. By pressing F2 at start up and going into your BIOS (the Phoenix SecureCore Setup you talked about) Without changing any settings look through it until you find the HDD, or the BOOT options, if it lists a HDD don't get excited as it should be there even if it was damaged and is now unusable. Did you have your laptop on Hibernate, they say to shut them down if your transporting. Since when they are off they park the HDD, but when they are in Hibernate the HDD really isn't off it's on stand by. Making it easy to damage since the HDD is ready to read or write at the click of a button.

Having dropped my Samsung R530 (nothing obviously broken), when I try to stsrt it it is coming up with the message:- "Boot From AHCI CD ROM: Operating System not found" Any ideas?

Hi tony prother,

"Boot From AHCI CD ROM: Operating System not found" error is because the system is booting the CDROM of the system and its not detecting an installed Operating System. You need to check if the system still detects the Hard Drive of your laptop on the Bios page. To go to BIOS reboot the computer and tap F2 on the system and on the bios page check if the hard drive is detected then go to then BOOT Tab select the hard drive as the first boot priority and reboot the system.

If the hard drive is not detected it might be damage, you can get intouch to a local tech to check and backup the files.

Thanks for using Fixya.

If that doesnt resolve, replace the HDD.
