MacBook 2012 Bootcamp problem

I was trying to install windows 10 on my MacBook Pro 2012, I was following apple tutorial (https://support.apple.com/pt-pt/guide/bootcamp-assistant/bcmp09f5f773/mac). I chose 100GB to windows partition. Everything was going great until I came across “no bootable device insert boot disk and press any key” message. I went back in MacOS to remove the Bootcamp partition to repeat the process again, but I couldn’t find it. Here are some prints from disk utility: enter image description here enter image description here

what can I do to undo and resize the original MacOS partition to try to do the bootcamp again?

Thank you in advance and have a great weekend!

MacPro, APFS, Bootcamp Startup Disk

Has anyone used brigadier to get a more recent Mac’s bootcamp installer and extract whatever bits allow APFS volumes to show up in the startup disk selector in the bootcamp control panel under windows? If so what specifically did you have to do?

Details:

Have a late 2012 MacPro. It dual boots Mac OS X Mojave and Windows 10. In order to run Mojave the video card had to be upgraded. The Sapphire RX580 pulse is acknowledged by Apple as a working “metal” card and seemed to be popular so I went with it. The problem is it doesn’t support boot screens. Not a huge issue until you want reboot from Windows back into Mac OS X on Mojave. Since Mojave automatically converts the install target to APFS there is no way to do it now short of zapping the PRAM or booting recovery and changing the startup disk that way. The lack of boot screens means no startup menu support when holding the option key.

I’ve done a lot of digging and I understand that newer Macs using bootcamp alongside APFS correctly show the OS X disk as a startup disk in the bootcamp control panel under windows. That is how I ended up with the question above- wondering if anyone has taken the time to figure out what drivers or what specific components in the bootcamp ESD for those macs changed and allowed APFS to work correctly with regards to the “Restart in OS X” bootcamp option under windows.

Lost my APFS partition after using EaseUS partition manager on Bootcamp

I used macOS mojave(APFS partition) and Windows10(Bootcamp). And I tried to expand Bootcamp partition with moving Windows OEM partition by EaseUS partition master. After this, I can’t find APFS partition installed macOS.

Do you have any ideas to solve this? (I am Japanese, so I’m sorry for my poor English)

can’t boot into windows 10 bootcamp but partition is still good

I have a Macbook Pro 15″ 2018 running High Sierra and I installed Windows 10 using bootcamp. I had duet display installed on both HS and Win10, and I installed Parallels Desktop 14 on the MacOS side and had it run the bootcamp partition instead of installing a new instance of win10. I think duet display caused some problems because the MacOS version was trying to mirror with the ipad at the same as the Win10 duet display running duet display (that was dumb, I know. it was a careless accident). It crashed/stalled and I couldn’t shut down or suspend win10 in Parallels. I ended up force quitting Parallels using activity monitor. Now I can’t boot into windows by holding option on bootup. However, I do have the Paragon NTFS for Mac that allows me to view NTFS partitions and all my data is on there and now backed up. I’d rather not have to reinstall everything if all it takes is fiddling with the EFI partition. Any ideas?

Mojave bootcamp assistant limits partition size

MacBook Air 2015, Mojave installed, 125 GB flashdrive

We had a VM for windows, but with installing Mojave, deleted everything additional down to bare Mac OS and tried to install W10 with boot camp assistant (BCA). According disk utility, MacOS is taking 27 gb (including W10 iso file), free 93 gb. BCA partition keeps 47 gb for Mac, with remark 8 gb free. It will not go lower.

I used Disk Utility to make a disk partition of 30 gb for Mac, 90 gb for second partition. No problem. I deleted that partition, again disk space 120 gb, free 93. Tried again BCA, no dice, will not go below the 47 gb for Mac OS.

Any way to push this lower? I would like to go 85 gb for W10, 35 gb for Mac. That should be enough for both OS and some working space for extra programs, all larger data files go through external drives or cloud.

Bootcamp error not enough space available on the disk

I have a problem when trying to install Windows on my MacBook Pro 2015 using Bootcamp, I am using MacOS Mojave 10.14. I have replaced the original SSD for a different one, bigger M.2 NVMe PCI-e SSD fitted with adapter. Although everything seems to work just fine, Bootcamp seems to have troubles with the partitioning. When I run Bootcamp assistant and try to install Windows, the support software can not be saved to the disk. This is the error message I get: "The Windows support software could not be saved to the selected drive. There is not enough space available on the disk." Even though I have split my 1TB SSD in half. (512GB for Windows) I have turned Time Machine off, made sure there was only 1 volume on the disk before installation… I even tried to install Windows using USB, which almost worked, but crashed several times right before the installation finished. I have tried several ISO files. Nothing worked. Is the main problem the replaced SSD or can there be a different problem?

Option key not working for switching in bootcamp. MacOS boot volume not in windows partition

When I restart the computer (a 2016 15-inch Touch-Bar MacBook Pro running 10.14.4 Mojave) and hold down the option key, the computer just boots into macOS. It does not access that “switching” screen. How can this be fixed?

Yes: I have reset the NVRAM multiple times

Yes: I can still manually boot in to windows through startup disk. The problem arises when I load into windows 10 and it can’t boot back into the Mac portion because windows can’t load the Mac OS boot volume.

The Mac portion recognizes the windows portion perfectly fine, but not vice versa.

Using external NTFS drive from windows on mac with bootcamp

I am new to StackExchange so please pardon, if my request does not follow all best practices.

My dad uses Windows 10 on a MacBook pro 2015 via Bootcamp. His backup data is on an external NTFS hard drive. He is unable to access the data.

I am using NTFS with mac via paragon software. I.e. I am aware of the different file types.

What I am struggling with is that, since he is running bootcamp, he is probably not able to use a paragon NTFS driver for mac, is he?

Is this a know issue? Can somebody advise on how to approach this? Happy to buy a Software like the Paragon driver, if that solves the quest.

Bootcamp HDD is now in a USB3 external enclosure. Can I boot my iMac from it?

I installed windows 10 on my iMac with bootcamp and it worked great. I have since upgraded to an SDD and the old hard drive is now in a usb 3 enclosure. I’d really like to be able to boot from that external – is this even possible without doing a new install? (I no longer have the install disk or key)

Can an eGPU work on bootcamp with a thunderbolt 2 port?

I aim to purchase an external gpu (likely this https://amzn.to/2UvNTeh) and am wondering if a thunderbolt 2 port will work with an eGPU on windows 10 bootcamp. I know there is a file for the mac OS to be compatible with Thunderbolt 2, but I don’t know if that’s possible on bootcamp.

If that is impossible, how efficient would a windows emulator on the mac OS work with games so I could play windows-only games/editing software? How much of a bottleneck would the emulator be on the eGPU?
