I have been trying to install windows 7 on my MacBookPro 8.3 (Late 2011). All unsuccessfuly. So far I have encountered these problems: 1) I have tried installing windows 7 by creating bootable USB using Unetbootin. It does boot in EFI, however windows installer complains about created partition being MBR and not GBT type. If I use gdisk to convert it, the initial installation goes through, but at the end of it it gives me an error of “Cannot update the computer’s boot configuration”. 2) I managed to avoid the latter issue by deleting all partitions from HDD, allowing windows installer to create new partitions on its own (Does not work if I leave Mac OS partitions). In this case the initial stage of installation fully completes, but when the computer re-boots, it gets stuck on grey screen. Choosing the HDD using option key gets me stuck on booting screen forever (I have waited for 8 hours for most of my “Loading” errors). 3) I have tried following Oleg Kokorin’s answer on this matter, creating a hybrid partition. But when I try to boot from Legacy OS – NTFS flash drive. I receive an error of “No bootable device – insert boot disk and press any key”. I have no more guides left to follow so would really appreciate any help on dealing with this problem. Goal – to install a windows 7 on my MBP. I do not care if it is the only system left on the computer or I have to dual with OSX as long as it boots at all. PS. I did manage to install windows 10 from EFI, but when I tried to install bootcamp drivers it crashed. I assume it is due to w10 being unsupported for my MBP mode. PSS. I have currently installed Sierra for the 5th time, due to it allowing me to disable SIP unlike El Capitan.
Please help!! Can’t start in safe mode. Tried command s, screen is difficult to read but believe results were all good.
Tried recovery mode, won’t load. Tried internet recovery mode – no good. ☹️ Any help would be really appreciated. Bought MBP from a guy on Facebook 3 weeks ago. Lesson learned!!!
I have a 2011 iMac with one Thunderbolt 1 port and one FireWire port. Is there a way to use one of those ports to connect the iMac to an HDMI laptop so that it can be used as an external display? Unfortunately this model of iMac does not have Mini DisplayPort.
Installed a new hard drive on a iMac 2011 27″: old drive would not boot (node errors which FSK cannot fix). This faulty drive was running High Sierra before it stopped booting.
Removed the old drive and installed in an external powered enclosure.
Installed new HDD — but remote install of OSX limited to Lion (10.7), as Apple remote recovery only reinstalls original OSX imac came with.
I cannot find any way to find the recovery partition on the old drive.
Tried to update OSX from app store but my account purchase list does not show any OSX (lots of my apps though)
Cannot check my Apple App store account settings as “To make changes to your payment information, you need to upgrade your Mac to the latest version of macOS.”(Which is what I am trying to do!!)
Tried to download El Capitan from the great Apple page set up for this, but on clicking ‘Get’ it says Paypal will send me a text to confirm the account, but that was over a day ago.
Also worked out how to use terminal (fsck_hfs -r /dev/disk1s2) to try to rebuild catalogue on the now connected external enclosure with old drive. Says it can’t be verified after executing command.
My question: So how can I upgrade OS, when I can’t access app store or Apple App store account, or find the recovery partition on what is now the external drive, and I can’t get a CD with OS?
Even if I could find the recovery partition, I cant see any information on how to use apart from starting the external disk in target disk mode perhaps? (which will not work as it won’t boot)
Running out of options…thank you good folk in advance.
The best thing I can think of is to fond some way to copy the recovery partition from the old drive to the new drive (as I can read the old disk), but where is the partition?

My wifi will be working and then all of a sudden I get the no internet connection page on google chrome. My Wifi status bar still shows a full signal but nothing loads. So I go to turn my wifi off, but I can’t get it to turn back on – the wifi status bar just stays blank.
I tried resetting and it didn’t work and I found an older post saying to toggle the wifi card on and off with some terminal commands, it works but it resets my computer every time (this is annoying) is there anyway around this? Better fix?
My 15″ Macbook Pro Late 2011 have a crooked GPU and won’t finish any reinstallation of OSX. tried to verbose it in installation and it hanged in hardware validation or something that make me believe the failed GPU obstruct OSX reinstallation. Tried all MacOS installer from LionX, to HighSierra.
I managed to installed it with Ubuntu 18.04 that somehow didn’t do hardware validation in order to install the OS. It work flawlessly and I want try my luck to install OSX again. So, my question can I make a new OSX installation and double boot it with already-installed ubuntu. All the tutorial I found was about dual booting ubuntu with already-installed OSX. How can I manage to do this scenario?
I am currently running OS X El Capitan on my early 2011 13″ MacBook Pro. I am thinking of upgrading to macOS Mojave, but would like to know if it would slow my MacBook Pro because of my specs?
Please see more info on the specs below:
I’m not using an SSD and my current available space is 140GB (total is 320GB), though I always make sure I don’t go below 100GB available space.
