Internal hard disk drive not found

What is the Boot Order in the Bios?

1st boot: [USB Floppy]

2nd boot: [USB Hard Disk]

3rd boot: [USB CD/DVD]

4th boot: [Hard Disk}

5th boot: [CD/DVD]

6th boot: [Network]

7th boot: [UEFI]

Can you move Hard Disk to 1st boot, save the change and exit the Bios?

Tried that but it didnt seem to help

Can you move the hard disk drive to another PC and see if the data is seen?

No, don't have another PC the hard drive will work with. Any other options?

Please call phone support.

Try another cable. If this machine has a "back plane" for HDD (no visible cables in front) try another slot and/or make sure cables attaching back-plane to motherboard are secure.

Exact same problem with my Area 51.

Was there ever a solution?

Have you recently installed automatic updates from windows? The windows software may corrupt alienware software installed. I found out that windows automatic updates was not recommended. I'm not sure what your exact problem is, but for me, to fix it, I had to call the tech support from alienware to reinstall my windows. Hope this helps.

Thanks for the quick responce. Yes this was caused by an update. I contacted tech support and after an hour lost contact as tracfone out of minutes. We were just about finished I was typing "bootrec \bootix" (or somrthing like that) and lost him! I am shure we were on the right track, I just need to know what to type for sure, and what to do next? i hope he will email me with those instructions.

The point of posting is to say that I believe it is fixable without a complete reinstall of windows, at least i hope so!

Dear fd, Are u able to solve the problem at last??

I'm having same problem with Aurora R4 that I ordered around Nov 20 and received around Dec. 5. For me, It's a random problem and usually only happens in the morning on the first boot. Internal hard drive not found with options for f1 retry, f2 bios or f5 psa. Usually changing anything in bios boot order will allow it to find drive and boot into windows. Also, just doing a hard boot (power off), then power back on will result in drive being found and successful boot into windows. Have had  three chats with tech support on phone. Was running bios A06 and had hoped flashing bios to A07 last week would solve it but it didn't. Today tech said it was hardware issue, mother board and hard drive. I have the 512gb ssd. They offered to send a tech to replace the parts, (probably will be refurbished, they said), or they could send me a new computer. I was hoping it could be resolved by changing some settings but they say that's not the case and it sounded to them like a connection issue and that they were afraid it would get to the point of not booting at all. I opted for the new computer. Am not looking forward to boxing up the first one and sending it back when the new one arrives. Also am not looking forward to starting all over again setting up the new computer. I do have everything backed up. With my luck I'm fully expecting the new computer will exhibit the same problems, especially since others have seen it as well. I received the first computer around Dec. 5. If the second computer exhibits the same problems I guess it will be time to ask for a refund if that will be possible. They did say the warranty would reset with the new computer. I'm having a stressed out day.

I solved the No HDD problem by switching the HDD mode from RAID to ASCH <- i forgot the term in bios.

However, i reached some rebooting problem in windows 7, and i am not able to boot into the Win 8 now. I will try resetting all stuff in later Dec.
