ASUS K95VB Notebook - UEFI Option In BIOS

Jul 26, 2014

Just got my hands on a brand new ASUS K95VB notebook on behalf of a friend. I used a USB with Windows 8.1 on it in order to format the hard drive and install Windows. The hard drive is 3TB. I remember trying to install Windows using the UEFI option in the usb startup menu but that didnt work so I proceeded on the non-uefi option.

Now the problem is that only 2 TB are shown and the remaining 1 TB is shown only in device manager as not assigned...

If I understand correctly, the BIOS should be in UEFI mode and then the hard drive should be converted to GPT and then install Windows.

But, no option in BIOS for UEFI to be enabled whatsoever. What on earth should I do?

No UEFI Tile And No Option / Function Key For BIOS At Startup

Aug 6, 2013

I am trying to boot from USB in order to start using Ubuntu but my problem is that when I go to the advanced settings - troubleshoot - there is no UEFI Firmware Settings, which, from what I have gathered is necessary to be able to boot Ubuntu from my USB flash drive. So far the solution that most people have is that there is no UEFI on that particular computer/type of windows 8, and on the startup screen to press f2, f11, esc, etc but there is no indicator as to what key is is on the ACER splash screen, similar to this. scn101.jpg

Therefor, I cannot get into BIOS?

Can't Get Boot Menu BIOS Option On Asus X750j Laptop?

Jan 24, 2014

My wife has a new Asus X750j Laptop.

I've spent the last day and a half setting it up.Now I want to make a system image of the C: drive using Paragon.

I do this from a bootable DVD, but it isn't set to boot to the DVD first in the boot order.

I've tried tapping the F11, F8, Del, Esc and F2 keys and it just boots into Windows 8.

My computer which has an ASUS motherboard, shows a message when I boot, saying select "Delete" to boot into the UEFI Bios.

But I can't seem to get either a boot menu of the bios option on the laptop.

UEFI BIOS Firmware Restart Doesn't Boot To BIOS

When I click the UEFI BIOS Firmware live tile via the change PC settings>update and recovery>recovery>etc. my computer reboots normally to Windows and will not open BIOS.

Windows Boot From GPT GUID On Notebook With UEFI

Aug 9, 2013

I have my main nbook (MSI GT683R-261CS), which have UEFI (AMI Aptio). However when I try to install Windows to (pre-created) GPT GUID sytem boot partition, Windows installation program kicks me to balls, that it can't be installed there.
In UEFI setup, there is no option to switch between MBR and GPT boot. Is there any utility, which will tell me, if my machine supports booting from GPT GUID?

I proceed in creating system boot GUID GPT by something like this:

list disk
select disk[=n]
detail disk
list partition
select partition[=n/l]
detail partition

ASUS Notebook Not Shutting Down Correctly?

Dec 3, 2013

So this morning my dad went to power off his ASUS K55N Notebook, and it didn't turn off correctly, the screen went black, but the system stayed powered on (had to perform a hard shutdown). He didn't perform any Windows Update(s) or install new drivers prior to this, he didn't change anything, and just now it did the same thing.

the Notebook was performing perfectly fine before today.

Network / Sharing :: ASUS Notebook - Default Gateway Not Available?

Jul 31, 2013

For the last week or so, I've been having issues with my ASUS notebook disconnecting from my wireless network or having a limited connection. This would happen maybe twice a day, but eventually I went online and I found that I had an outdated driver for my Intel Centrino Wireless N-2230, and as soon as I downloaded the latest driver, my notebook would disconnect every 5 minutes or so. Running the troubleshooter just keeps returning the same thing; Default gateway not available. It also does this annoying thing where it'll disconnect and reconnect over and over again, so quickly that the network sharing center can't even register it's happening. I've tried resetting the WINSOCK, IPv4 TCP/IP, and IPv6 TCP/IP stacks, I've tried a clean boot to see if it was a startup program affecting my connections, and I've changed my power settings so they don't turn off my adapter. I even tired booting my computer in safe mode, which didn't work.

Debugging :: BSOD / Crashes And Freezes While Gaming On Asus Notebook A56CB

Jun 9, 2014

Bought a new laptop almost a year ago, i was never able to find the cause of the crashes.

Here some specs

- Intel i7-3537U CPU
- Asus K56CB motherboard
- NVIDIA GeForce GT 740m Dedicated GPU
- Intel HD Graphics 4000 Integrated GPU
- 4gb 1600 Ram, single stick
- Windows 8.1 (had the same problem with win 8)

On every game i play i get random freezes, random crashes, random BSODs, some games do crash more frequently than others, I've tried older drivers, I've also formatted my pc but the problem is still there...I am not using any antivirus, windows defender is enough for me.

What gets on my nerves the most is that even on old games like quake live do crash and sometime it also gives me BSODs, the fps are constant and quite high but i randomly get freezes (about 0,5 - 1 second long)...

another example, im playing SMITE, i get 80-150 fps but the game crashes every 2-5 mins, this game rarely gives me BSODs, when im lucky the game wont crash for 20-30min, but its very rare. the gpu can reach 80-85C. With "crash" i mean black screen with a window saying "Game.exe has stopped working"

There are other odds things happening on this notebook, for example i cant access to the bios while booting, i can only access to it once i log to my windows account, another strange thing is when i left click any file sometime it takes 10-15 seconds to get the "open, open with, copy, paste, cut etc.. window opened". I've also noticed that sometime while gaming my disk usage get to 100% for an instant and when that happens i get a lag spike/freeze...

If no way to find the source of my problems ill build a desktop and than ill keep sending the notebook to warranty until they fix it . I've still got 1 year of warranty, I've also sent it once already but they only changed the hard disk, and it didn't solve the problem too ...

Setup Installation :: Win 8.1 - Convert BIOS To UEFI

Apr 14, 2014

I have windows 8.1 installed on 120gb ssd. I also have a 1tb HDD too. So I was trying to install Hackintosh/Linux when I noticed that the System Reserved partition was on my HDD instead of the SSD. So, I used easybtc to migrate my boot files to my SSD. I deleted the system reserved partition. Now I want to convert my BIOS to UEFI. I have Z87 pro mobo.

I tried this tutorial: [URL] ....

But it seems to be geared at the C drive, where I don't have room for that 350mb as disk utility wont let me shrink it.

Edit: would downloading a third party partitioner, shrinking C about 350mb, or whatever is the minimum, and then use that new space as described in the guide work?

Maintenance :: UEFI Bios Settings For Windows 8

Apr 11, 2013

what settings are required in the UEFI Bios to run recovery USB/ disks or Linux live CDs. It all used to be so simple. The manufacturer seems unaware that it supplies UEFI systems - so I am working blind. Have tried boot CDs and USBs but all have booted straight into Windows to date. I don't wish to change settings I have no understanding of.

I have a Medion /Lenovo desktop with an AMI UEFI Bios (12 July 2012) and Aptio Setup.

The following seem relevant are supplied as enabled in "Bios":

Intel Rapid Startup Technology
Quiet Boot
Boot Select Mode [UEFI]
UEFI Hard Disk BBS Priorities - Boot Option #1 - Windows Boot Manager
Secure Boot - Secure Boot Mode [Standard]

What do these all mean and what effect do they have on how Windows 8 runs and how boot drives run?

Setup Installation :: Switching From Legacy BIOS To UEFI

Jan 29, 2014

Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.

When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up Windows 8 just fine. What I'd like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under UEFI.

Can Turn Windows 8 Installation For UEFI Into BIOS CSM Mode

May 31, 2013

On my computer there is a pre-installed Windows 8 which works fine for UEFI boot (Secure boot not necessary).

Now when I switch in UEFI setup at boot time the UEFI mode into the CSM (BIOS) mode and restart then Windows 8 is not starting any more.

As far as I find out an UEFI-based Windows 8 can only boot with UEFI mode enabled.

So my question is: Can I turn an existing UEFI based Windows 8 installation into an CSM/BIOS based installation (=a Win8 which boots successfully even when I enable CSM in UEFI setup) ?

If yes: How do I do that?

Cannot Install Windows 8 In UEFI Or Normal BIOS Mode

Jun 2, 2014

I cannot install windows 8 in BIOS or UEFI mode.

it's getting boot and install only in EFI mode. after trying to reinstall it won't allow me to select the disk partition, as it gave me the error "

Windows 8 cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks." i tried all the given solutions on GOogle. even i cannot recover or refresh using windows 8 environment. many times it gives me BSOD. cannot vonvert to MBR as it says it cannot be done on virtual HDD.

tried many things nothing works, need to install windows 8 after every 1 or 2weeks, many a times my BCD data gets corrupt, and windows wont start. Also tried many things to repair this, but only thing that works is reinstalling windows 8.
That gpt or MBR error was solved by selecting UEFI:CD drive. in boot options by pressing F12 after inserting the disk.

My system configuration:
System Info Utility version

Setup Installation :: Migrating Windows 7 And 8 From BIOS To UEFI Computer

Jun 13, 2013

Question: How would you approach this migration?

I just bought a copy of Acronis True Image 2013 with Plus Pack. It appears that this is all I need as True Image will install the new motherboard drivers as part of the migration process. But do I stay with MBR or move to GPT?

Presently both Win7 (on a 120GB SSD drive) and Windows 8 (on a different 120GB SSD drive) are both MBR format. I don't want to start over from scratch. That's why I bought the Acronis 2013 with Plus Pack.

Setup Installation :: Installing Windows 8 / 8.1 On External HDD UEFI Bios Only

Jul 21, 2014

I'm trying to install windows 8.1 to an external hard disk (solid state drive 128 gb usb3).

I've tried easyUFEY WinToUS creator and AOMEI Partition Assistant Standard(Windows to go) with no luck.

My bios has UEFI option only(no legacy). On my old laptop it works just fine(I had the legacy option) but now, I cannot do that anymore.

I'm pretty sure it's a bios boot issue and I don't know how to fix it. I've tried using GPT partition instead MBR, Still nothing.

The laptop is a sony vaio duo 13 and I have no legacy option in bios
