Operating system not found – Samsung RV511 Windows 7

CHRISE321 · 06 Jul 2015

Hi,

I have the above computer which I purchased in 2011,following a recommended Windows 7 update a couple of months ago, the laptop locked. I powered off the laptop and could not viewmy main hard disc’s(C or D) when the computer rebooted, however I had access tomy external drives

A local so called Microsoft specialist(rogue) visited meon my instruction with the intention of recovering my data from both these drives, which he didto an external drive which I supplied him. He removed my hard disc from my machine in order to do this

Today, I have reinserted the hard disc into my computer,however I am getting the above message “Operating system not found”

I have selected both Boot-up options:-

· F2 – Setup, there appears to be no option to Boot from an external drive in the setup

· F4 – Recovery, I cannot enter the Windows menuto perform this task, laptop appears to hang

Any ideas would be welcome or am I just wasting my time withthis laptop(hard disc) which despite this problem appears physically in verygood condition as it has been well looked after

I confirm my laptop was protected by the latest version of Norton and Malwarebytes at the time of my problem

This my first post on this forum, I trust it is in the correct location and your advice would be most appreciated

Many thanks

Your HDD is inside, why are you looking for an external one? (or I understood you wrong)
F2 and set boot order to HDD (might show as it's name). Save and exit.

If this doesn't work boot with a Windows Repair Disk and see if your OS is recognized.

Yes correct HDD disc is in my laptop, I have already selected F2(Setup), but there appears to be NO option to select a boot disc, I cannot access my HDD, this is the reason I am looking to boot from an external drive on my computer

My daughter has a later version of my Samsung(Daughter=S3511), in perfectly good working order, I have today compared F2 options in the setup menu on both her and my computer, there is no difference

In summary, how do I select a boot disc in the Setup menu(F2) on a Samsung laptop as there appears no such option in the menu.?

I thank you for your response

Well, external won't work if there is no OS on it either.

Can you take a photo of the BIOS menu? Would help a ton to clear confusion.

Photo's as requested:-

My problem Operating system not found - Photo 002.jpg
Setup Menu's(F2) - Photo's 003-009.jpg
Response for laptop when I select Recovery mode(F4)

I have attempted to select F9(setup defaults) within the setup menu, but this does also not work

Many thanks

Ok, you almost made it but missed it by an inch :P

Go into BIOS, boot menu, Boot device priority and press enter to see the list, adjust the menu: 1 can be CD/DVD, 2 set the HDD

HDD should show it's model name.

If still doesn't work, there may be no OS on the disk indeed or a bootmgr problem.

See Troubleshooting Windows 7 Failure to Boot, try a startup repair (but read other options too of course)

Ok, you almost made it but missed it by an inch :P - I am sorry but I do not understand what you mean, are you referring to one of my photo's, I can take further if necessary

How do I access BIOS, within the setup menu(F2) I cannot find within the menu a location to select the boot priority order

I thank you for your response

It is the Setup menu (F2) - see the third photo of yours. Your cursor was exactly on the option to be selected.

@GokAy, I thank you once again

I have entered the Boot menu, I enclose a photo of the Boot Device Priority for my laptop, I have not personally made any changes to date within this boot menu - The CD at the top of the list(No 1) means nothing to me, I assume it is a cd disc associated with my rogue Microsoft man

Having researched this problem on the internet, I discovered this website/SW for recovery:-
Download Hiren?s BootCD 15.2 | HBCD Fan & Discussion Platform

I have inserted this CD into my laptop, sadly nothing which I expected, however my laptop physically recognises my CD, would you suggest I move HDD into to priority 1

I would be most grateful if you have any further suggestions(following my latest posting) prior to me attempting to moving HDD to priority 1 or exploring the other options in your earlier posting advice regarding bootup options

Regards and thank you

No need to change boot order, if no CD is found it will try the next boot device, which is your HDD.

It may be that your HDD lost its formatting etc. Download Partition Wizard free and make its bootable media. Then boot with it and take a photo of it, post here, lets see how it looks like.
