I've purchased a new SSD hard drive for my laptop. I put the SSD into the HDD's place and put the HDD into the DVD rom place. at first there was no problem, the computer detected both of them and they were listed in the boot option. when I tried to install windows on the SSD, it said that this drive is MBR and it should be GPT. I converted it to GPT using AOMEI, and tried to install the windows but it gave me this error
windows cannot install required files. the file may be corrupt or missing... error code :0x80070570
at first I thought that my device or the files had a problem. I tried with different windows files and different flash drives but the error occurred every time. then I realized that after I've changed the SSD type to GPT, it is not shown as a boot option in the boot menu. I converted it back to MBR, it came back to boot options!!
I formatted my old windows drive on the HDD, hoping that it would help, but it didn't! and now my HDD is not listed in boot options either!!
no GPT drive is being listed in my boot options. when I convert the SSD to MBR it is one of the boot options. and windows cannot be installed on an MBR drive. I can't even install windows on my old drive! it gives me the same error. I used to install windows 10 and others on this HDD without any problem and it is gpt. I don't know what to do! my bios is updated. my laptop is Asus x450cc
please help me!
You shouldn't have to convert from MBR to GPT. You should simply have unallocated space on the SSD, while booted in UEFI mode and install Windows onto the unallocated partition (this will create all require partitions for you). If you are creating partitions for the Windows installer you are doing something wrong. If you want GPT, you must disable Legacy Mode, when before attempting to boot into the installation environment. – Ramhound – 2019-02-02T18:42:52.983
when I disable the legacy mode, it does not boot to the flash drive to install the windows! but I will check it with mbr as you said – Mohammad Talebi – 2019-02-02T18:51:57.360
If it does not boot to the flash drive, then your installation media was not created to be compatible with UEFI mode. If that is the case, then you cannot use GPT and must use MBR. You could also create the media the correct way, I suggest, just using the Media Creation Tool. You are unable to install Windows, on a GPT disk, because your installation environment was booted while in Legacy Mode. – Ramhound – 2019-02-02T18:54:24.360
windows installation is in progress now, hope it goes well! one question. why do you think my old HDD is not listed in the boot options now? – Mohammad Talebi – 2019-02-02T19:00:47.663
as you said, I converted the SSD to MBR and unallocated it. windows installation started without saying that the drive should be GPT. but the same error occurred again! do you think my windows media has a problem? – Mohammad Talebi – 2019-02-02T19:07:23.327
Yes; I just said that’s the problem – Ramhound – 2019-02-02T19:29:53.153
