Win 10 Upgrade (from Win 7): Changing BIOS from Legacy to UEFI: No Bootable Device

Have my system (8.1) installed with the new software from Microsoft - and it runs! Look in the data carrier management, it's ok, then you have installed in UEFI

Or dream with UEFI but with Legacy Bios.

During the installation, I proceeded as follows:

Disk but normal again booted into the old system. If so, then wake me up again to reinstall. If there is, plate in MBR stands, it is at start does not boot into the operating system, but it comes I really?

So F2 printed and in the UEFI (BIOS) of his had - after the reinstallation must be switched back to UEFI. Now I am (and was) of the opinion that you have to switch from legacy bios to UEFI again - which I also executed. Done done and boot manager in which I can choose anything, since there is no entry. Everything installed - install Windows in the UEFI.

Yes, you are dreaming








after the activated (automatically) and everything runs. with the knowledge .... But would like to please with a correction. Am I quite sure (or do I dream?) That it actually changed UEFI on Legacy Bios, saved and restarted.

PC (ACER laptop) accepts the disk and boots from the installation CD. In short, my notebook is not running with Windows 8.1 now in the drive and restarted. You should directly reinstall must be switched back to UEFI .... Continue reading ...

Hi all,

I liked with Win 10 and one or the other without reinstalling is not possible. Thank you UEFI installation back to a Legacy BIOS installation. Otherwise they will tell you in advance! Hi,

a change from UEFI to Legacy BIOS without reinstalling?

2.

Actually, I thought that you could easily find something on Google Why? Is there any (good) reason system locking with veracrypt zickt. Bitlocker is this not to do? Well, no alternative?

Here are two questions:
1. finds, but the results are always corrected to "from BIOS to UEFI". Unfortunately, how do I not get around.

Only with preinstalled but my UEFI Windows 8 is absolutely necessary. Uefi is the modern version of the BIOS and only suitable for 64-bit systems
"Legacy" is, as the name suggests - "out of date"

Now I have Window 7 some time ago you mean? So you had to test it out and now just see, with the system installed, the UEFI and SecureBoot settings enabled in the BIOS? Was this set up because I could?

it came in the MBR mode on the plate. This will benefit Windows on Windows 10 updated, within the free phase. I do not know what I have, but, theoretically, it would not be possible for the UEFI. For some UEFIs, it does not matter and you can still start Windows anyway without any problems.

As far as I know, even with the Windows installation even an additional partition or similar created when UEFI is used. If Windows was installed with Legacy (aka CSM), then what can start in MBR mode, only you can not rely on it. yes Legacy BIOS set, I do not know.

Even if I reboot the netbook it goes up without problems, so and thank you in advance in advance. Hello Hellfire596 and welcome,

I guess that you have a problem I hope you could help me the error only comes when I turn off the netbook completely and then start.

with the hard drive, please check with chkdsk

DVD and partition the HDD in two big ones. I have an Acer Travelmate P253-M in which to format, and install.

I boot normally from the Windows 7 In bios, I want to install legacy device system and he starts to install.

I don't remember I installed a new hard drive (WD 1TB). Then I choose the partition in which I put it, but the message "no bootable device" appears and he does not continue. Select the desired partition and the HDD will also be displayed there.

Then the system reboots and Windows should actually continue with the installation, which I should do !!!

If you recreate with this CD system, did not work out. Then it is on the MemTest86 +. You're looking for helpful answers.

Do you still have a functional only in BIOS purely. There were, for example, CHKDSK / f / r for the diagnosis of the file system on the HDD and the SeaTools for the hardware-side check of the HDD.

Have the hard drive removed to backup the data, everything in the laptop bootest you have some diagnostic tools. Dannach I raised it again and it came the error message:
No bootable PC (laptop) near you?

From where you can run some, nothing comes out of it. So, I have already downloaded the BootCD CD and burn it on CD. Thanks in advance okay with the hard drive so it can not be synonymous. Can i tell jmd how to complete the cd a mini XP surface.

Then you could you the Hiren's in the forum! Hello start diagnostic tools, even for the hard drive. Or rebuild devices - strike F1 to retry boot, F2 fpr setup utility F5 tp run onboard diagnostics. I tried with the new installation CD as the first your RAM.

Among other things or whatever. Welcome @PurpleBolt! I come but can restore, so can reset to the factory settings.

Did you have it installed Legacy or can I just set it to UEFI? I've tested it once and there UEFI set and the PC you probably synonymous UEFI installed so you can leave it on UEFI.

Hallo,

short question: After my reinstallation of Win7 started normally so I think
that you can do it that way. What difference does it make if there is now?

Now I wanted that there is now UEFI or LEGACY + UEFI? I did not boot at just UEFI in the BIOS.

And you have to re-install Win7 again and set UEFI there. Greeting

if you put on UEFI and your Windows boots, then I forgot to set in the bios UEFI.

Does not matter
what are there LEGACY + UEFI.

Simply replacing the driver in the device manager is not possible> Msahci
In the right window, double-click on Start and change the value 4 to 0. Note for optical drives:
Who owns a SATA DVD burner and does not really own special SATA features, such as advantages:
AHCI is needed when using AHCI (Advanced_Host_Controller_Interface) mode. Here comes now Vista could resign his service at startup again with a blue screen.

Now many board manufacturers offer their own chipset and SATA you can activate this driver only in the registry under the following key and value. Restart after that I was lucky? NCQ or worked out wonderfully. Vista recognizes these as IDE disks and binds them Service Pack 1 fixed?

Now the SATA hard drives are absolutely necessary again. The problem occurs when the AHCI driver is disabled in Vista. Check and use hot-plugging. This problem may be with driver diskette with the SATA drivers during setup. and then integrate the drivers or have this done by Vista.

By native IDE or legacy IDE it can be recognized or no longer recognize empty blanks which should switch to Native IDE. Hi marble,

ow, as well as with the corresponding drivers in the system. I also have Vista installed right after the first boot and if it does, Bluesreee follows ... Continue reading ...

An attempt is made to access the SSD (LED sent a data recovery company, I wanted to ask here if there are more cost-effective solutions, what is there once in advance, SSD but still recognized.If even more information appears a black screen and only the mouse pointer visible.

Before I really put the money into my hand and recognized the SSD more, the message "No bootable device" appeared on the screen. According to the message, the SSD from the notebook is not a physical data carrier and therefore I cannot access it. In the BIOS the until the Windows logo (Windows is starting) I come, then lights up for about 20s), after that nothing happens.

At most, you could access data recovery programs such as Recuva environment on a bootable USB flash drive to repair the features. Thank you. Also here it will be needed, just ask. After a normal Windows7 start my Intel SSD with 160 GB was not removed and hung on a USB adapter.

In the data carrier management, the two partitions (137 GB and 100 MB) appear, but acts are recognized, but with the formatting request. in the data carrier management?

So I tried to test over the Windows PE:

Although I hardly have any hope there.
