Samsung NP270E5E boot options problem

August 17, 2018 at 16:17:55
Specs: Windows 10
Hello

My laptop was running into a blue screen error, so i decided to format and install a new copy of OS using bootable USB drive with windows 7.
But first i went to every option on the BIOS and reset it to default.. Now it wont show any boot device in the BIOS except for windows Boot Manager which also doesnt help when selected. I tried many combinations of BIOS settings but still couldnt help..

With the usb plugged in, try togglinq F10 during boot.

"so i decided to format"
Formatting is not enough, delete all the partitions during the install.
When they are all gone, Delete & Format will be greyed out & the drive will read Unallocated.

I have several questions to help clarify. Which OS did you have before formatting? It appears your laptop came with Win8 but your specs say Win10. What error message was on the blue screen? Did you attempt any repairs before formatting? When booting off the USB, did you delete the old partition(s) & then create a new one? Why did you change the BIOS settings? Defaults are almost never the best settings but they're a starting point.

I suggest you reload the BIOS defaults & then make any changes you're 100% certain of. Boot off the USB again. Delete the Reserve partition & C: partition, create a new partition out of the unallocated space, & then continue with the installation.

If F10 fails, turn off Secure Boot in the bios.

Thank you for responding..

-I deleted all the partitions at first when the BIOS could still allow me.
-I installed windows 7 which when install would give me a blue screen error with the second reboot.
-So i thought it was a problem in the BIOS then i reset all the options available...
-Now a new problem arises; i can no longer use my bootable USB flash drive to install.
-All the settings in the BIOS are set correctly i.e ADVANCED
*FAST BIOS --->[Disabled]
*AHCI Mode Control --->[Auto]
*USB S3 Wake-up --->[Enabled]


BOOT
*SECURE BOOT --->[DISABLED]
*OS MODE SELECTION --->[CSM]
*PXE OPROM --->[DISABLED]

I HOPE THE ABOVE SETTINGS ARE ALL WHAT IT REQUIRES TO BOOT FROM MY USB FLASH DRIVE.
But now, when i restart my laptop pressing F10 it give me a screen written "Boot Menu" on the left and "App Menu" on the right....
-Under Boot Menu there is absolutely nothing listed but i thought it was supposed to be showing a list of boot options medium like HDD, FLASH DRIVE, SATA ........ e.t.c as it did before i reset the BIOS to default/factory settings.

-On the right side (App Menu) it list only; "1. Setup".
-When i select setup, it leads me back to the BIOS screen....

MY MAIN PROBLEM IS THAT THE BIOS DOES NOT LIST OTHER BOOT MEDIUM DEVICES, EVEN IN THE BOOT PRIORITY SETTINGS.... OR EVEN WHEN I PRESS F10...

-I tried so many suggestions that i followed from the internet but they still failed...
-I once removed the CMOS battery but to no avail...

ONE MORE THING
If i set OS MODE SELECTION --->[UEFI AND CSM OS], then restart nd press F10, on the window that appears under Boot Menu, it gives me "1. Windows Boot Manager" which when selected the screen will flash and come back to the same screen of Boot Menu and App Menu

1.The laptop came pre installed with windows 8.
-i upgraded to win10 just to keep up with technology.
-After a while, i felt the laptop was all slow on win10.
-i decided to format everything to install win7 because
i felt it could be handled better on this machine.
-At first when the laptop still allowed, i installed
win7 which would after a second reboot give a blue
screen of Death with a code.
-i did the formatting/deletion of partion and installed
win7 repeatedly about 4 times which still lead me to blue
screen error everytime after the second rebooting.
-thats when i did the reserting of the BIOS as a troubleshooting
measure.
-I did not attempt any Repairs because i wanted everything wiped
away so that i can install win7 from win10.
-Yes i deleted all the partions and created new one.


"""I suggest you reload the BIOS defaults & then make any changes

partition & C: partition, create a new partition out of the unallocated
space, & then continue with the installation.""""

Yes i did all the above as you suggest.

Thank you for your continued assistance...

F10 is not failiing but there is no boot device list, it just an empty window of Boot Menu..

But if BIOS settings is set like this;;; --> *OS MODE SELECTION --->[UEFI AND CSM OS]

then Under Boot Menu it will only show ---> ""1.Windows Boot Manager"" which does not help load the installation from the bootable USB flash drive.

"which does not help load the installation from the bootable USB flash drive"
What did you use to create the bootable flash drive?

I have bootable flash drives one installed with win10 another with win7...
i used rufus and Windows 7 USB DVD Download Tool to create each of them respectively...

Either way i don't think its the problem because even if i have not put the drive in the pc i still must be able to view a list on Boot Menu after i have press F10

Did you get any messages at startup or popups with Harddrive warnings before problems started to appear on WIN10? I have a feeling your HDD was slowly failing and now completely dead.

If you insert a bootable USB, is it listed in the boot menu or BIOS?

The harddrive is fine because i even tested it from a different laptop nd i was able to install an Os from that laptop...

It is not listed and nothing is listed at all under Boot Menu not even at BIOS... All that is listed is windows boot manager as i already indicated in my replies on comments above...

i need help on how i can make those options on boot menu to appear....
even the HDD itself must be listed according to my previous experiences..

See if there is any thing here that helps. UEFI is what you need.

Rufus
Select the GPT partition scheme for UEFI computers.

There is one thing i want to confirm...
-On the BIOS setup, we have the security tab..
-If i navigate to the security tab,
then
Secure Boot Configuration
it gives me 2 options;
"Reset to manufacturing Default AND Change to customized Signatures"
if i select; "Change to customized Signatures"

it displays the message; "Are you sure to change to customized signatures?
Warning! PK will be deleted and the platform will be changed to setup mode.
Secure boot will also be disabled automatilly."

I tempered with this, so i wanna know what it means by; "PK will be deleted" maybe the PK is deleted
hence setup mode as per the warning above??
Im just asking anyway....

To me, that appears to be where you need to be.

Googling is the way on the other questions.

i tried all these but to no avail, i think you do not understand my problem here...
My problem is in the BIOS... The BIOS can not display Boot device list in the Boot Menu...
To display items in the Boot Menu after pressing F12 or even directly in the BIOS at the BOOT tab.
this does not require a bootable device to be inserted in order to show boot list as the ROM and the HDD could always appear....

I need to make the Boot Priority List appear thats when i can continue with my installation...
So far i tried many different Bios settings which failed... Even the settings i used at first which were working now they can't work...

On may BIOS screens I have worked with, may have two places that you need to set in order to set a drive as bootable. On one screen you make HD, USB, DVD, etc as 'Bootable' individually and then you will be shown the options in the boot order screen. In order for some drives (HD, DVD, etc) to appear on the first screen they need to be detected by the BIOS though since USB is integral, it does not need to be plugged in to offer the option. I hope that this help.

Other settings in BIOS that may not be optimal after resetting to defaults is the CPU settings, the Memory settings, the primary graphics, as well as a bunch more. Minor ones like Num Loc to on, Wake on LAN to off (stops computer from waking during the night if plugged in to LAN), and many other small ones included.

You have to be a little bit crazy to keep you from going insane.

Some claim you need to Hard reset your BIOS to fix the "BIOS Problem":

Not recommended if you're not tech savy.

You don't need UEFI with Win7. You can use it if you like, but you don't need it. Unless you have a huge HDD or simply prefer UEFI, I suggest you disable it & use the legacy BIOS. Also, considering your laptop came with Win8 preinstalled, it means the BIOS is configured for it & UEFI is most likely the default.

I don't know if this is useful: https://support-us.samsung.com/cybe... It might be the same as posted in response #14 but those links don't seem to work. Are you adding any characters to the links?

" It might be the same as posted in response #14 but those links don't seem to work"
That's because MikeDt has copied & pasted the links from post #11.
This forum does not put the full/complete link into a post.
To get the full bootable link, it has to be taken off the browser.

I have followed the links and seems like nothing helps...
All the options suggested on this thread i have tried all of them but still i can find the boot list...
On the Boot Menu there should be a list like the following whether i put a bootable device or not;
*CD-ROM Drive
*Removable Devices
*Hard Drive
*Network boot

All this can not show
