BIOS UEFI Dual Boot Order

Q: BIOS UEFI Dual Boot Order

Hi guys, I'm trying to properly dual-boot Windows 10 Edu 64bit and Kubuntu 16.10 64bit. The problem is that on startup it's impossible to start GRUB, Windows is loaded automatically. Is there a way to change UEFI boot order? I tried several methods but Windows always overrides my changes; I managed to load GRUB only once by renaming the Windows OS Loader path to the GRUB one, but after I booted to Windows once again, it overrode my settings creating a new Windows OS Loader entry. These are the methods I've already tried: Renaming the path as I said up here through bcdeditUsing EasyUEFI to change boot orderUsing efibootmgr in KubuntuUsing boot-repair in KubuntuUpdating GRUB in Kubuntu While on my desktop I have a BIOS setting that lets me change UEFI boot partition, I don't have anything similar on this laptop. Let me know, thanks.

Preferred Solution: BIOS UEFI Dual Boot Order

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Heys guys, I'm hoping I can get some help with this. I have a Lenovo y410p. It has 2 drives, one with the OS (120GB SSD 40mm N.2 NGFF) and a data drive(1TB HDD)
My computer recently crashed when I was installing a piece of software, (Bentley MX Road, it's a road alignment package.) When I restarted my laptop I was greeted with a lovely message informing me that winload.efi was corrupt. That was fine so I did a bit of research to fix it involving getting a recover DVD and going to the command prompt to rebuild BCD. That didnt work for me as it didnt detect windows. I tried to see what was up with the SSD using DISKPART & CHKDSK. Neither of these showed the SSD. They only showed the HDD
So now to take a step back, In order to get the recovery DVD to boot I had to change the boot option in the BIOS from UEFI to legacy support. This showed me a list of bootable devices (HDD, SSD, DVD etc.) When UEFI is selected only one option is available which is the Windows boot manager. This is followed by the serial number of the HDD which does not have any OS on it.
I have tried using f12 which give me the windows boot manager option and nothing else. When I select this, it boots me into the error message.
So to get to the root of this, how can I change the boot order when the BIOS is set to UEFI so I can repair the winload.efi file on the SSD. Thanks for any help.

A:Changing boot order when BIOS is set to UEFI

You change it the same way as before. Usually you can do it withe the OEM software installed on Win8.

You may have to turn off Fast Boot if set.

Hi, I have a HP Pavilion 15 n204tx Notebook with Windows 8.1 running. Now I would like to install a SSD by replacing the optical drive. I am not an expert and I did some digging. I heard that before I install Windows to the new SSD, I should change settings in BIOS to AHCI concerning my hard drive. My Problem now is that I can't find it in BIOS. Where can it be found and maybe changed? Is it really needed to change BIOS mode? What are my alternate choices?

I have a new Precision 7710 with a 2.5 inch 1GB SATA SSD (system boot=Disk0) and a 1GB NVMe PM951 SSD.
I have been attempting to install Windows Server 2012R2 on the second, M.2 SSD (Disk1) into a GPT, NTFS partition.
Since this system has no DVD, I made a bootable UEFI thumb drive with the contents of the .iso installation for Server 2012R2.
The thumb drive boots OK and I can begin installation, but when it comes to choosing the target for installation, the M.2 SSD is not visible in setup.
The M.2 drive is clearly visible inside Windows 10 Pro as the D: drive.
So...I mounted the .iso setup file in Windows 10 and ran setup.exe. The install began and could see the target M.2 drive, and began loading files on the second SSD. It then attempted the first of several restarts that come with this process with the new Server 2012 R2 environment.
It sucessfully modified the Windows Boot Manager before the restart, then restarted, and the setup program gave an error because it could not find the target partition on the second SSD.
The setup environment then modified the Boot Manager to "Windows Setup Rollback" and proceeded to enter an infinite loop, attempting to delete files from the unreachable M.2 drive. I manually choose Windows 10 on the boot menu, and once booted changed Windows 10 back to the default OS.
I've tried several things (turning off Secure boot, changing from UEFI to legacy bios--it won't boot at all that way) , but I can't get that second disk t... Read more

I have a notebook toshiba satellite L850-1HU with UEFI

Default is win 8 os, recently upgraded to 8.1.

Now I need to win 7.

I have a professional license N sp1 x64 and then supports UEFI

Is possible to combine the systems in dual boot and both in UEFI mode?

I see from your guides that for installation the UEFI is necessary partition in a certain way.
What should I do if I want to leave intact the UEFI partition of win 8 (5 partition)? I just make only space for win7(1 partition) that will use the same 4 partition UEFI of win 8 or i make other 5 partition???
And which of the two systems will handle the boot? I can decide I?

and the warranty? restores factory work?

If I change hdd, and install win 7, when I put the old hdd, it works as before removing it?

A:Satellite L850 & Win 8 UEFi: How dual boot UEFI win 7 ?

If I change hdd, and install win 7, when I put the old hdd, it works as before removing it?

Yes. This is how I do any OS tests\'dual boot'\experiments etc with zero chance of damage to the original boot OS\hd. Am keeping a bunch of old HD's for the purpose. The downside is the slight risk for some mechanic\connection problems, just be careful, remember to power down! So if you don't find it troublesome to switch HD's, IMO go ahead and try that route.

Hello! I recently acquired an Acer V3-771G and I want to dual-boot Windows 7 Ultimate x64 and Windows 8 Pro x64 and I was wondering if it is recommended to change BIOS with the UEFI found on Acer's site. Also, if i should do that, when is it right to switch from BIOS to UEFI? In the beginning, after W7 is installed, after W8 is installed, etc. Note that I have some experience with dual-boots, but none whatsoever with Windows 8.

I suppose this can be different depending upon the motherboard or PC manufacturer but hasn't it been your experience that the boot order is most often the CD/DVD ROM drive as the first boot device by default when you receive a new computer?

A:UEFI Boot order...

Well for convenience most people set CD/DVD as first boot item. However if you are security conscious, you would set HD to first boot plus set a password for the bios. The reason is that somebody who has physical access to the computer can boot a Linux LiveCD and bypass all Windows security and access your files.

I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?

Windows 8.1: HP Pavilion 2475ea Desktop PC.
I have Secure Boot turned off. I have Legacy Boot turned on, but do not think that is needed.

This link gives me instructions to boot from CD but they seem not to make sense from No 2...

...in that at 5-6-7 it seems to require me to select the CD then boot to Windows from HDD then restart and do the same again, but this time select CD again, or something??
I expected to set the device, then restart the computer and it would boot from the device, not restart Windows as described.
I was able to boot from a WinPE 4b CD.

I then decided to try changing boot order in the UEFI BIOS. From then on the HP (F9) described menu showed 'Windows Boot Menu' only under UEFI Devices. I could only boot from CD after putting the order back to 'Windows Boot menu' at the top of the order list; after which, as long as the CD was in the drive the (F9) list showed the CD drive as selectable to boot from.

I find this, after 30 years of normal BIOS, to be confusing.
Can somebody help please?

My HP Pavilion 15-ab238na always resets the UEFI boot order when it (re)starts, is there a way to prevent this? I've just added a SDD to the notebook (in the DVD reader slot) and cloned the Windows partitions to it, so I have 2 bootable Windows discs in the notebook (SDD and HDD).  I'd like to leave both of them there for a while. The notebook has recognized the new Windows system on the SDD and added it to the UEFI boot sequence. The original HDD is first in the UEFI boot order and the SDD is second. I've been trying to make the notebook boot from the SDD by changing the UEFI boot order. No matter what changes I make to the UEFI boot order, when I restart the notebook the boot order is reset to it's original state, with the HDD first and the SDD second. I've tried using both EasyUEFI on Windows and efibootmgr on Ubuntu (run from a DVD) to change the boot order. I can make it boot from the SDD by configuring the Windows Boot Manager, but I'd prefer to do it by changing the UEFI boot order. Is this possible?

When I access my UEFI during startup, the Boot Priority section is either empty or shows unrelated drives attached. I can select the drive from which to boot by clicking on the Boot Menu, then clicking on the drive desired.

I purchased a new Intel SSD and installed it as the "C" and "D" drives and was happily booting from that SSD until I added new HDDs to my system. I now have four HDDs plus the SSD. One of those HDDs still contains the original Root C bootup and Windows 8 system on it. I frequently now find the system, reason unknown, may choose to boot from the HDD rather than the SSD.

I cannot find the method for directing the UEFI bootup menu/priority steps... my goal is to have the computer boot from the SSD, which if it were to fail, then would secondarily boot from the HDD original Root C.

The computer arbitrarily changes the SSD from drive designation "C:" to "J:" and the HDD to "C:"... how to specify the SSD as the "C:" unless it fails or is removed?

Reboot and enter UEFI. Can you see change your boot device priority?
On a Samsung tapping Esc at boot may give you a boot menu that will let you select a boot device but SecureBoot should still be disabled.

Hi People

I have a dual boot PC. I had to rebuild it recently because I put a new mobo and a new cpu in. I decided to be different this time and installed Winxp on my C drive and Win7 on my D drive. In my old rig the order was reversed.

Originally I thought this would be okay until it came to installing Rollback RX. Then I discovered that every time I tried to install rollback it either failed to install or it only protected my XP drive. I want it to protect my Win7 drive because it is my default boot.

I decided to start all over again this time installing in the reverse, with Win7 on C and WinXP on D. However I am having nothing but problems doing this because now the Win7 disk is not being recognized as having all the drivers and I can't get an internet connection on WinXP!!!!

So I'm thinking there might be a simpler way to do this. I put the contents of the disks on a Norton Ghost backup before I started doing this. Can I restore the contents of D on C and C on D? I can do it physically because both are the same size and both are ntfs. The problem is booting. If I do this my pc won't boot. So is there a way I can fix this?

I contacted Rollback RX three days ago and they haven't responded.

I have a new laptop, a toshiba p870, that came with windows 8 preloaded. I needed windows 7 for compatibility reasons with a few programs and after a bit of research and struggle I eventually got it installed on a second hard drive in the computer but in the process I had to change the bios settings to disable secure boot and enable CSM. After that Windows 8 will no longer boot even if the second hard drive with windows 7 is removed. I have no way to access the bios in order to change this setting back, the only way to access it was by going through the windows 8 recovery and troubleshooting settings, inserting a windows 8 disc (from a previous installation on a different computer, non-uefi) didn't offer the uefi firmware options in recovery mode. What can I do to restore access to windows 8 on this system?

EDIT: I finally figured it out. You must hold shift as the computer shuts down in order to get the toshiba logo and the option to enter the bios with F2 to show up at startup. This isn't a very convenient setup for dual boot, having to change between CSM and UEFI to choose operating systems but it works.

I purchased Lenovo Z500 with Windows 8 installed on it. When Windows 10 upgrade started rolling out, I moved to Windows 10 Home.I have been running into some issues with my activation so had been trying to reset to factory default but that is also not happening.I created a Windows 10 UEFI bootable disk and went to the BIOS to set the USB as the first bootable disk in the list but it doesn't show up there.Now it did show up earlier (without me changing any setting in BIOS) when I was trying to do recovery using System Image Recovery option with Recovery Image in the USB. Anyways, now I'm trying to install the Windows 10 from scratch and then Ubuntu 16.x alongside Win10 however stuck at this very phase.I read quite a lot about UEFI and Secure boot and see that in my Boot menu UEFI is enabled and Secure Boot is disabled. Please refer the screenshots.Can someone explain me in detail that with this setting in BIOS what could be going wrong with my steps where UEFI bootable USB is not detected?Also, in addition to that if someone can point me to the latest document/discussion for Dual Boot with Windows 10 and Ubuntu. I might have it bookmarked but just in case.I would appreciate quick and detailed response.Thank you in advance.

Ok, this has been dealt with in various places but not to my total satisfaction. So bear with me if the answer is hidden somewhere in the forum.

I've got an oem asus with 2 hdds the first of which has Win 7 64 home pre-installed via uefi boot manager. It is a gpt formatted disk. The second disk is empty and is set up with mbr. I wish to dual boot onto the second disk with Win 7 32 Pro but fear a rejection due to the fact appparenly Uefi will not manage 32 bit installs/boots. More to the point , will the mbr variance on the 2nd disk somehow make for an exception to this 32bit 'prejudice' on the part of uefi or simply make matters worse? My bios has a single option regarding a legacy setting connected with uefi which is disabled. PxO... or rather. Gregrocker seems to think obviating the problem with 2 physically separate installs (i.e. Hdd disconnect) will allow a Bios based boot as opposed to a Uefi/Windows managed one. Is this workaround a sure thing and my only option or is there a practical way to go the classic route with the auto boot loader screen on start up? Perhaps a better way to put it is..on dual boot systems is it true that you can't have BOTH uefi and the bios directing the show. You gotta choose one or the other. Frankly, to my novice mind this whole problem seems to be a regression from the XP days. Anyway, a definitive answer from you all would be more than welcome. Thanks loads.

EasyBCD lets you edit your configurations while iReboot lets you switch between operating systems with a single click. Got them, use them, recommend them. And, they are free for personal use.

Hi there, I hope this is the right forum for this question.

My son has an i7 custom build computer and the previous owner gummed the computer up good with malware etc. The current setup is Windows 8, but our goal is to install a fresh copy of windows 7 Professional 64-bit which we have purchased "intended for distribution with a refurbished PC".

This is a bit of a project for us, so we are taking our time with it, and hopefully learning something along the way.

We are trying to wipe the HDD completely on the machine, but we are unable to run DBAN to do so, because every time we restart the machine it keeps booting up in Windows instead of DBAN. I have gone into BIOS and changed the order of the BOOT to read from the CD-ROM followed by the USB before the C Drive (I have copies of DBAN on both USB drive and CD-ROM). But it is still not booting. Not sure what to do???



A:can't boot DBAN trying to change boot order in BIOS not working

It is possible you have not created a bootable CD/USB. Use Rufus for example. https://rufus.akeo.ie/

Also provide motherboard make/model please.

I got a SSD now in my system connected to the first sata port with win7 installed
My previous (mechanical) sata hard disk who was prev. setup on this port is still usable and also has win7 installed on it. i wnat to use it as a experiment setup.
If I connect this old hdd to another sata port say sata 1 or 2.

Can I choose to boot from either the new SSD or the old sata-hdd and run win7 without problems using the BIOS boot order?

I read some scary stuff about this scenario could mess things up because both both drives used to be 'C'

Also I have my BIOS setup with AHCI nowbecause of the SSD. My previous hdd used the standard sata-mode. If I use this old mechanical sata hdd which has windows7 on it and use AHCI in bios will it boot/work?

A:Boot from one of 2 attached drives with BIOS boot order no problem?

As long as you installed windows independently, with the other drive unplugged, there would be no issue choosing either one to boot from the bios.

I doubt if the hard drive will boot in AHCI mode, but test it to see.

I am currently running Win2000 Pro with FAT not NTFS. I'm not a great gamer do but have a couple I would like to load, but of course Win2K cannot support them. So I thought - how about a dual boot system? Hard drives are ok for it, 2 each with 2 sizeable partitions, so easily arranged. BUT, I am led to believe that I cannot install Win98SE AFTER Win2k. Is this true, and if so is there NO way around it except reinstalling Win2k as well?

Hey Guys,

I've recently installed Windows 7 Professional on my Windows XP machine. It's installed on a partition of the same drive that XP was on.

At the boot menu when it lets you choose between the 2 OS's, it's defaulted to the Windows 7 one, and I can only get to XP if I manually choose it. I want to keep XP as the default option, but I don't appear to be able to change it (I did this before with Windows 7 RC1 without any problems)

When I got to msconfig and look at the boot configuration in Windows 7, it only shows Windows 7 as the default option. There is no other option, Windows XP doesn't show up there where it should

It's the same when I look at the boot config on XP, there's no sign of Windows 7 there!

Anyone any ideas how I can sort this out? I need to add XP to the list


A:Solved: Trying to change boot order (Dual Booting)

Ok guys looks like I sorted it -

There's a great program called EasyBCD which showed both of the OS's and allowed me to sort it all out!

Hi there bleeps :D
I got a sony vaio laptop, and it has windows 7 OEM on it. Tried to install Linux on it on another partition, and the installation was fine and finished. Then I got into the windows and used BCDedit to add a new value for the linux distro I installed. Now, when I boot the laptop, it gives me 2 options, win and linux... but if I run linux, it gives me an error and doesnt find the bootloader.
If someone can guide me through the process I'm ready to erase all my data from the HDD and repartition everything. My only aim is to be able to dual boot Windows 7 with Kali Linux.
Current partitions:
1- SONY partiton (dont know what the hell that is) ~260MB
2- Recovery parition ~20GB
3- EFI boot partition ~260MB
4- XXXXXXX partition ~300MB (has no name and i don't know what it is for)
5- Windows 7 installation ~70GB (C:/ drive)
6- Linux boot partition ~300MB (/boot)
7- Linux root ~12GB (/ )
8- Linux home ~40GB (/home)
9- Unallocated space ~450GB
Hidden partitions
NTFS partition
Ext4 partitions
Thanks, bleeps 

A:Want to dual boot Win7 with Linux on a UEFI-based laptop.

I don't know Kali Linux at all, but I have installed Linux Mint 16 on a UEFI Windows 7 system.  Current versions of Linux Mint, Ubuntu, Fedora and OpenSuse at least have support for UEFI.  For Kali Linux, it appears you will have to make a custom ISO with UEFI support - https://forums.kali.org/showthread.php?271-How-to-EFI-install-Kali-Linux
To install Linux Mint, dual booting with Windows 7 in UEFI mode here is what I did...
- Starting point was Win 7 x64 installed in UEFI mode, GPT partitioning scheme on all attached disks, and 100Gb unpartitioned space on one of the disks.  If you need to re-size existing partitions to create space use Gparted.
- Boot Linux Mint DVD in UEFI mode (this involves going into the BIOS, and in the Boot Override menu choosing the name of the DVD drive with UEFI in the name, as per below).  NB This is important - if the installer is not booted in UEFI mode, it will install in Legacy mode and this will not work if the existing OS is installed in UEFI mode.

- Choose "I want to do something else" aka custom installation in the installer
- Created separate root, home and swap partitions (swap, if using, should be equal to ram).  The root and home partitions were formatted to Ext4 FS.  I allocated 20Gb to the root partition and the leftover free space to the home partition.  Mount point for root is /, and for home is /home.
- Find the existing EFI partition created by ... Read more

I've create 2 partitions, 1st partition is Win7 SysPrep and the 2nd partition is Win8.1 Sysprep
I install Win7 and press Ctrl-Shift-F3 to form SysPrep, same as Win8.1 in 2nd partition.
I made this becuase I've 25 Dell new Win8.1 Computer which are UEFI. So I want to make a master computer which has both Win7 and Win8.1 with SysPrep in it. Then I want to clone it to the other 24 Dell computers.
CASE 1 : 2 different partitions with 2 different Windows :
If I install both Windows like above, when Sysprep Generalize Win7, it works fine. But if I SysPrep Generalize Win8.1, it's fine also, but never can boot again back to Win7. The start boot option is like this :
Windows 7
Windows 8.1
If I choose to boot Windows 8.1, it's fine. If I choose to boot Windows 7, it ever boot to Windows 8.1. It means nomatter I choose to boot which Windows, it all goes to Windows 8.1 ?????
CASE 2 : 1 partition for Win7 + Win81.VHD :
I install Win7 (C and press Ctrl-Shift-F3 to form SysPrep.
I create a Win81.VHD in Drive D: , imagex Win8.1 install.wim in it. Also press Ctrl-Shift-F3 to form SysPrep.
Sysprep Generalize Win7 is OK , SysPrep Generalize Win8.1 is also OK. But after that I can only boot to Windows 7 fine, when choose to boot Win8.1 , it always restart and back to the boot menu ?????
Can anyone help ? Thanks a lot.

I am choosing which OS to boot by changing the boot order in my BIOS. To me, this seems clean and simple. I built 32 bit XP on one disk, then removed that disk from my system, installed a different disk, and built 64 bit W7.

When both disks are installed, I change the boot order to select the OS I want, and each OS sees and can use the files on either disk.

Am I asking for trouble here, or is this as clean as I think it is? What I want is one set of user document files which can be used from whichever OS has been booted.

There are no problems with doing it that way its just a PITA. with minimal work you can have a bootloader where all you have to do is click the OS you want to run. You need to use a tool like bcdedit. there are instructions for itis use here BCDEDIT - How to Use .How this helps and let us know if you need help with anything

I am trying to delete all the files from an old HP (XH545) laptop running XP. Its screen doesn't work, so I have it attached to a remote monitor. I have both a bootable floppy and bootable cd which have [email protected] Kill Disk. My intention is to boot one or the other and erase everything on the hard drive.

Problem: I am unable to get into my BIOS to change the boot order. Since I have to do a Fn-F5 to switch over to the monitor, I am unable to get there in time to see when to hit F2 to edit my BIOS. I have been trying for several hours to "guess" when to hit it, still with no success. I'm not even sure I would be able to see the BIOS screen anyway - maybe you have to get past that for Fn-F5 to swap out to the monitor.

If I let the system boot normally, I can swap over in time to see it loading Windows XP.

Question 1: Is there any way to change the boot order from within Windows (or from DOS prompts)?

Question 2: Lacking a positive answer to #1, is there any other way to delete all the files from the hard drive so I can dispose of the laptop?

Hey guys! I have an old dell laptop here with windows 7 on it. im trying to reformat the drive and install a fresh copy of 7 ultimate but cd drive is not on the boot order. when i enter the bios and try to change anything in the boot menu, nothing happens. it literally wont let me. when i hit the change value key over cd/dvd rom drive it just beeps at me. i know some ppl have often said a solution to this is to disable "secure boot/csm/UEFI" etc. but this system doesnt even have those options. it does have a comparable "computrace" but it is deactivated and inaccessible. How can i get the system to start from the disc drive so i can reformat and install a fresh copy of 7?

I had Vista on C: drive and later installed XP on D: drive.
Boot order was then Vista - XP, worked ok. I then changed the boot order where XP to be the default . And now the boot manager does not allow me to even choose Vista, but goes directly to XP. The changes I did in Vista.
I have "restorepoint delete" fix active ( System Restore Points - Stop XP Dual Boot Delete)
Restoring the fix does no difference to this issue other than making boot.ini visible for changes on the XP side, but without options for Vista.

Has my Vista gone "hasta la vista" or is it "see you never more". Is there some means of getting it alive again?

I don't have the option in windows to boot back into the UEFI setup. In my motherboard bios setup there is an option which allows for the selection of UEFI, Legacy and UEFI or Legacy, When I change this to UEFI my pc wont' boot and the error message is that no UEFI partition was found.

I think it may have been deleted when I installed Windows 8.1 initially because i had to convert from MBR to GPT. Or so i read on one of the forums.

Is it possible to restore my UEFI partition so that I can use windows to enter the bios setup. I've had the boot on ultra fast and it took me a week to get into the bios without using the delete key. I had to use Gigabyte utilities which include drivers that crash windows. So i want to remove them again ASAP.

Any help appreciated.

A:UEFI option instead of Bios boot

Well to get back into UEFI mode you will have to reinstall in UEFI mode there is no other way, Sounds like some how your OS got converted to MBR so It may not boot either MBR or UEFI but you can't convert back to UEFI you have to Reinstall. If you have data on that disk you need to recover you can pull the drive and hook it up USB to another computer and recover your Data.

Dear Bleepers,
this is our strange situation:
My friend has a samsung laptop Ativ Book 2 (np270e4e) with windows 8.
After few problems when updating to 8.1 (it deleted the o.s and gived only a bsod saying that there is not any os installed), she decided to buy and install windows 7 so she disabled the uefi, setted the legacy mode and the boot priority first to the usb hdd (we have a bootable iso).
Parphaps every time we restat doesn't boot from the disk but showed the windows 8 bsod. Naturally the f4 for restore gives anoter bsod for not founding any partitions!
We discovered that it's not possible to boot from the disk, so we made a bootable usb driver with the official iso.
After that we picked up the hard disk and delete all partition from another pc and disabled all the boot driver but the usb hdd. After that it booted from the pen drive with official w7 iso.
The installation was completed in about 30 minutes. We started to install the drivers, chipset, intel storage but:
the next reboot it showed this message: all boot options are tried. press f4 key to recover with factory image using recovery or any other keys for next boot loop iteration and it was a continue loop and can't access the bios.
Strangely when the usb driver with the official w7 iso was inserted it said: "press any button for starting with usb driver"  and if we don't press anything windows started normally.
So we tried to install another time thinking it was a driver conflict but the second ti... Read more

A:All boot options are tried, no (uefi) Bios

Seems to be a common problem with Samsungs. See this thread and the post by François.  Can you access the boot menu by tapping F2 instead of holding it down? See if you can access the computer with Fatdog64. You will need to burn the iso file or use Rufus to create a bootable USB. If the USB does not boot then use GPT as a partition scheme in Rufus. 
According to here F2 is the boot menu for a Ativ Book 2, 8, 9 but F10 is the UEFI access key. Try tapping F10 at boot.

I just bought sony vaio S Series, with original Win 7 home basic 64 bit. But, many of my device such as printers, network wifi and etc not support for win 7 64 bit. Now, I want to install win 7 32-bit on my laptop. But, My CD Win 7 bootable won't boot at my laptop. After i check bios, i found something strange on boot menu orders, if the boot in "Legacy" mode, that laptop will boot from my cd. But if "UEFI" mode, looks like the system has ignore my boot cd, and go straight to windows 7 64 bit. Has anyone solve this problem? Will somebody help me to solve my problem? Thanks anyway

A:if UEFI mode on Bios, Cannot boot from CD... :(

You can install 32 bit to an EFI BIOS but it has to be in Legacy mode, with EFI Boot disk removed from the BIOS Boot order, and the HD wiped with Diskpart Clean Command so installer can reformat it from (EFI formatted) GPT disk to the normal MBR disk.

Follow these steps to get a perfect normal Clean Reinstall - Factory OEM Windows 7.
