Help, cannot upgrade to Windows 10 on Lenovo Y50-70

Question

Hello everyone, I'm using a Y50-70. From yesterday until now, I cannot upgrade it to Windows 10. I'm using Windows 8.1 Single Language shipped with it. I've tried many ways: - Use wuauclt.exe /updatenow to force Windows Update download Windows 10. After few minutes "Preparing for installation", it says "Update failed. Please try again" - Use Media Creation Tool to update. I tried to choose "Upgrade this PC", no luck. Always generic error "Windows 10 installation has failed" When I choose to create USB bootable disc, I run setup and after processing to 24%, it stopped with same error "Something happened". - Follow other suggestions, I've changed Region in Control Panel to "English (United States)". Same error again. - Even when I downloaded original ISO from Microsoft website and create a bootable USB, it always "Something happened". No more info. These things are driving me mad. Anyone has successfully upgrade your Y50-70 to Windows 10, please help or share your way to do. Thank you very much.

This is kind of disconcerting. I did the reserve and did ALL the latest 8.1 updates and then finally my Windows 10 said it was ready. I read an article that said to right click on the box window that appears when you reserve and then choose check your upgrade status and after that loads, you can also check your compatability report to make sure there are no compatibility issues. I have done all that. I have also backed up all important files to an external HDD in case of failure. I don't know if any of the above will help the OP, but it may list any possible compatibility issues. Maybe your original version of Windows 8.1 is not activated? you can go to Control Panel > System to see that your copy of windows is indeed activated as if not activated, it may cause a failure. That could be a good reason to use the OKR feature. Lastly, seeing that you are overseas, is your 8.1 version a US English version of Windows? If not, perhaps that is why all the tools are failing because maybe you have to download and install whatever previous type installation you had before with Windows 8.0/8.1? I would think performing the Compatibility check as described above may tell you if you are trying to update with a wrong version? Just a thought. Now then, speaking of OKR or other possible problems updating such as I read the latest BIOS update could also cause failures, but specifically speaking about OKR, there are numerous threads out there with all kinds of advice, etc but for me it is too much information and some information may be outdated. So I have a few questions maybe someone can help me BEFORE I leap into the Win 10 arena? 1. I know after upgrading to Win 10, I have supposedly 1 month to downgrade back to 8.1 using the Windows downgrade function. The biggest quuestion I have is, will upgrading to Windows 10 delete my OKR option? 2. I have the Y50-70 Touch UHD with 500 GB SSD. What is the best method of backing up the OKR media for just in case? I have seen several cloning programs mentioned and the Pendrive thread, but I am just wondering what is the best and safest way to ensure the OKR works.I have a 2 TB external HDD I am currently using to perform manual backups with so maybe I could clone the SSD and if so, best software option?   3. Or is the OKR really not necessary if I have the Windows Media Creator tool on the USB drive (I have one for Win 8.1 and one for Win 10)? Is using the Media Creator Tool method better or worse than using OKR? 4. Lastly, in case of catastrophic failure, are discs available from Lenovo? I have found nowhere in the support section that mentions being able to purchase recovery discs and no, my Novo button does not give an option to burn my own discs. All I can do is make a System image file backup and honestly, I don't even understand that. Does that system image file then restore my OKR if I choose to restore from that system image? I'm sorry for so many questions but as I stated there are so many threads on the partitioning issues and restoring OKR and the DIY Pendrive thread to me is very confusing and seems to contradict itself in several steps. I just want to be certain of having a functioning computer if the update fails or I end up with the BSOD. This is my first time using a computer with UEFI and OKR that does NOT allow the burning of recovery files. I have gone through all the WIN 10 FAQs but they do not address these issues. Anyways, thanks in advance if anyone has any answers to my disjointed and probably silly questions. As I get older it seems computers are getting more difficult to understand or maybe I'm just resistant to change lol Thanks again and good luck to the OP with his issues! And I hope I don't have the same problems but I will let you know if I do! EDITED TO ADD: Does anyone know if the nVidia Driver issue with Win 10 forced driver updates has been resolved? Or, if I update, does that mean I will have those issues that were discussed on the web between the forced drivers from microsoft instead of the PROPER drivers from nVidia? Or is it best to sit tight and wait for resolution? I do not use dual monitors so that problem won't affect me but I also heard some nVidia issues of bad flicker were also reported. I checked the Windows compatibility tool and no the GeForce GTX960M is NOT listed so for me that means it is currently unknown if compatible. This is another reason I would like to know if the OKR will still function, just in case I lose my screen during update. lol
