Upgraded to windows (from factory default windows 8) 10 while it was still free. Wiped the drive and tried to reinstall windows 10 (home) and all I got was an error saying that can't install on non gpt partition. Turns out the only way can figure out how to boot usb is via legacy mode. Plugged hard drive into desktop machine and says all the partitions are in fact gpt. Used rufus to burn image to usb, made sure that is gpt as well. For fun, tried the system restore function, but fails right away. I just deleted the windows partition (not the entire drive).

A:how to boot usb in uefi mode (not legacy) for inspiron 3531

When you reinstall there are some critical partitions.  You cannot leave any of those of the drive and reinstall Windows 10.  Data partitions should be OK.
To boot a USB drive as UEFI, assuming your system has that capability, you have to format the USB drive as FAT 32.  It must use an x64 bit version of Win 10.
When you boot you should be able to see a Boot Device Menu.  Look for something that shows as UEFI and boot to that.  If you don't see a UEFI option, the Bios may be set incorrectly or the USB drive is not configured correctly.

Hello,

I've installed Windows 10 and Ubuntu using UEFI.
But, now I created a bootable USB for a Linux that does not support UEFI, but only Legacy.
I mean, when I plug the USB to my laptop, the UEFI does not recognize it, only the Legacy BIOS does.
Is it possible to simply proceed to install the other Linux using Legacy mode? Or it will cause problems?

Thanks

A:Installing some OS's in UEFI and some using Legacy BIOS

I am never a fan of using dual boot. I have Windows 10 installed on a separate GPT SSD and Linux installed in MBR SSD and run them separately using Boot Menu so they are completely independent from each other.

I did mention in your other thread that dual booting using MBR is preferable which you can set the Windows boot manager and GRUB boot loader separately. The traditional way is Linux override the MBR and took over the booting process for both Windows & Linux. The non traditional way is to put the GRUB Boot loader in its own partition then use Easy BCD to set up the dual boot, this way they are independent so if there's an update/upgrade from either one, you won't break anything. In addition, you'll get a nice GUI dual boot Menu from Windows, not the ugly GRUB.

Here's an example:

GRUB controls the booting process for both Windows and LinuxPut GRUB in its own partition and use Easy BCD to set up dual boot.
NOTE: During Linux installation, you have to tell Linux not to use sda (MBR in Windows) but its own partition.

Hello,

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.

Any help would be greatly appreciated! I've found a couple articles but I just want to make sure I'm headed in the right direction and if maybe there is a safer and easier way to get this done...

This computer came with WIn7 and was upgraded to Win10. I would like to make it a dualboot (with Windows as the MBR) with Ubuntu. However, My BIOS is "Legacy" and I already have 4 partitions (the unused space is not usable by Linux). Can this laptop's BIOS be upgraded to UEFI without reinstalling Windows (I want to preserve all my applications and settings in WIndows). If so, can you point me to instructions in detail? If not, recommendations for any alternatives, such as what to do (& how) with the 3 partitions other than WIndows (C: is the main WIndows partition of course; D: is Recovery; I have no idea what the other two partitions are since they do not appear in Explorer and E: is the DVD).

Hi all,

Currently having a wake on lan issue with a certain computer.

The machine is setup correctly but the windows boot information is stored in a 100mb UEFI partition, and when the computer wakes on lan, it will not boot windows, just sit at a blank screen.

When it wakes on lan it is trying to boot from the legacy device (same blank screen happens if you choose to boot from it from bios)

ive tried updating the bios but no luck, all settings seem to be as they should be.

Is there some trick to get it to load the UEFI MBR, or is there a safe way other then reformatting the machine to move the MBR over to the legacy device itself?


Thanks for any help.

A:Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS. Next check BIOS Boot order for an EFI Boot Disk: remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SEL DIS 0 (after confirming Windows 7 target HD #)
CLEAN
CONVERT MBR
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

I built my computer from parts I ordered from Amazon, and installed Windows myself. I didn't fathom the differences between GPT and NTFS, and just picked NTFS format for my installation. I've since discovered that Secure Boot isn't possible without bios being in UEFI mode, which I believe requires your OS to be installed on a GPT drive (someone correct me if I'm wrong about that). I know that when I tried just changing it from Legacy to UEFI in bios and rebooting, I ended up in a shell program with no inkling of how to get my machine to boot. Fortunately I was able to discover how to get out of the shell and back into bios, to change it back.

So, how difficult would it be for me to get my system switched around so that I could enable Secure Boot?

If I make a disk image of my boot drive, which is currently NTFS partitioned, can I reformat it as GPT and then restore using that image?

A:I installed with NTFS and legacy bios, how hard to change?

So, I got a Inspiron 3537 i5. Nice laptop for it's price. Downloaded all the manuals, made my recovery DVDs. All was well in my world.
First thing I noticed is that there is no info in the manuals for tweaking the BIOS and since it is my first experience with a UEFI bios I was a bit disappointed. Is there a manual available for it?
Next I upgraded ATI Drivers to 13.12. I am an old user who always knew that updates were usually a good thing to do. Got in the same problem as many others with PC screen not waking up from sleep.
Thought I would do a recovery from the disk, but after trying various combinations (Ctl+F11, F8, F12 etc) I couldn't find a way to boot in the Recovery console. I did the recovery from my DVD and the laptop works fine.
Does anybody know how to add in UEFI bios a boot option to the Recovery partition? I undersstand that I have to create a new boot option using "Add boot option" and the two options available are to boot to the 1st (windows EFI) or 2nd (recovery partition), but the path for the recovery efi file to be loaded is unknown (+ you can't have access to the recovery partition to see the contents of it from windows). Any suggestions?

Asus G73sw Laptop that I have used every day for the last 2 years.

So, I got the message: "Reboot and Select Proper Boot Device, press any key" so I tried another working HDD that has windows 7 on it; same message. I took apart the computer and checked the connections and cables. One time, during the constant restarts with other HDDs, I got the message "A Disk Read Error Occured." When I entered the BIOS menu, It recognized the HDD. Also, on the Easy Flash, I could see that HDD and its files.

Finally was able to load windows with UEFI mode. I am unaware what this is, but I assume it will work for now?? I have made no updates to windows 7, installed no drivers or programs recently, and am unsure why BIOS won't load any of my HDDs to windows, when BIOS clearly sees it.

OK, you cannot take a hd with windows already installed and put it in another system then expect it to boot. Not going to happen unless the two systems have very similar or identical hardware.

This allows windows boot mgr to take over the boot process. This is not the only difference; there are many. UEFI uses GPT table, can address larger hd, and a lot more. Here is an article that explains uefi in more depth;

I presume this code is given because it cannot find the Dell Recovery application since it (as well as the entire UEFI partition) is now gone after I reformatted the HDD.

UEFI has some advantages over BIOS,such as:

I am not a happy camper with Windows 8.
I am confused with the Legacy and the UEFI boot methods. The reason I am confused I think, is because I read to darn much on the Internet. One bit of confusion is with respect to changing from UEFI to Legacy. It would appear from some comments that if I do that, Windows 8 won't boot anymore. I would have to change back to UEFI for indows 8 to boot. I also read that changing back to UEFI could be a major problem when trying to access the BIOS. No, I am confused. My ultimate goal is to set my laptop up to dual boot Windows 8 and Ubuntu. Like I have been doing for the last multiple years with XP and Windows 7.
Helpful comments would certainly be appreciated.

A:UEFI/Legacy

I don't quite understand what UEFI is, it is firmware, or is it Microsoft's new Boot GUI? I've set my systems to boot Legacy mode, and since I did that, I have no trouble getting into Safe Mode.

Does UEFI access your BIOS as well? That's what I'm worried about. The idea of not being able to access the BIOS from outside Windows 8 makes me itch. I think the Legacy Menu may allow that though - You can set it to Legacy, and if you can't access the Bios, then you can switch it back. I forget the command lines to set it, but they are in a tutorial here. It's BCDedit.

Hi, I just purchased the HP x360 Spectre, which came with Win 10 Home and UEFI/SecureBoot turned on. The boot disk is GPT. Also, there are 4 partitions on the drive out of the box, as listed in the : EFI SystemRecovery PartitionRecovery ( D: )Windows ( C: ) This is my first Windows above 7, and the first that is not Legacy BIOS and MBR boot disk, so I'm a little lost with all this. I need to backup the drive before making changes to the new laptop using my Macrium Reflect Win7-based PE USB pen drive, but when I disable SecureBoot and enable Legacy Boot and move USB key to the top of the boot list, it boots Reflect under PE OK, but no drives are shown in Reflect to back up. I'm not sure at this point if this is because Version 5 of Reflect doesn't support UEFI (although I'm not sure that's a factor as I've booted), or some other factor resulting from UEFI and GPT. I know Reflect V5 can backup GPT drives, as I do it now, but have only imaged MBR drives. There are newer version of Win PE; Ver 4 based upon Win 8, and Ver 5 based upon Win 8.1, which might solve my problems. I'm trying that next. If anyone has any insight, it would be much appreciated. Also, are UEFI and BIOS connected in some way to MBR and GPT, so that one requires the other, or can you mix and match. For example, could I have machine using UEFI and an MBR boot drive, or vice versa? I'm just not sure what, at this point, is making my drives not appear in Reflect. Also, is there a way to conver...

My XPS 8700 originally came with Windows 7 Pro, 64.  I since upgraded to Windows 10 Pro, 64.  I only now noticed that BIOS is setup for Legacy.  If I attempt to setup for UEFI MY drive is not recognized.  A check shows that the drive is setup for MBR.  I thought all XPS 8700's came setup for UEFI.  Am I stuck with Legacy or can the new drive be setup for UEFI???

A:XPS 8700 Legacy or UEFI?

I'm not 100% sure but I think UEFI requires drives to be partitioned GPT.
Remember, backup your Data.

And don't forget to backup your data. The conversion will format the drive.

Hello, first of all thanks for taking time helping me with my issue.

That`s the case:

I wanted to recover an Image-Backup done with a Backup Software, but the Boot-CD does not Boot on my PC. I have an Windows 10 64-Bit System.

While trying i found out it does indeed boot when i change the Bios from UEFI to Legacy.

If i recover the Image in Legacy-Mode and after that i change it again to UEFI - will Windows boot up or will there be Problems?

Is there any way to make the Boot-CD work also on UEFI?

Thanks in advance.

If your PC or laptop supports UEFI and legacy mode then the following tips may help you. Legacy enabled:If the bios setting is legacy enabled then hard drives and USB devices will normally boot.  If you are using two independent hard drives that are not connected by boot manager then the UEFI boot hard drive will always boot first before the legacy hard drive unless the bios allows you to change the boot priority. Legacy disabled (UEFI mode):If the bios setting is legacy disabled then only UEFI devices will boot.  You may run into no hard drive selection menu, no boot option menu or Boot Device not Found followed by a message Hard Disk (3f0). USB flash drives boot considerations:If you wish to boot up a USB flash device using Windows 7 repair, Windows 8 repair, Windows 7 or Windows 8 installation media then be sure to create the flash drive formatted as FAT32.  You may notice a bootable flash drive showing twice in the boot menu, one marked UEFI and one not marked UEFI.  Both will boot up. The popular MS Windows 7 USB WIndows installation media creation tool will create a NTFS flash drive using a Windows 7/8 iso file in NTFS format which is not bootable in UEFI mode. It works fine in legacy mode.  To get around the NTFS issue, create the flash drive in NTFS then copy the contents to your hard drive, quick format the flash drive to FAT32 and then copy back the contents back to the hard dr...

My system has several drives, two of which are 4TB drives. The two 4Gb drives are using GPT partition schemes. However, I'm booting off of a 240GB SSD which is using a MBR scheme.

When I installed my current motherboard, I did a fresh install of Windows 7. I didn't know much about UEFI, except that I hate it. Now I discover that there is an option to boot in legacy mode. I know in linux I can convert an existing system from UEFI to legacy mode by changing the EFI partition.

My question is, can I convert an existing Windows 7 install FROM UEFI TO legacy mode? If so, how?
