Question

after i installed windows 7 on my imac using bootcamp i deleted intel usb 3.0 host file and i regret it now, all my usb ports dont work now and i cant use my keyboard or mouse so i cant do anything on my pc not even login

because i wanted to play some pc games but only have a imac i decided to buy a windows 7 disk and then install it on my imac using bootcamp. it worked and i have windows now but i needed to make some room on my drive, its stupid to delete something without knowing what it is i know but sadly i deleted intel usb 3.0 host. after the uninstall my usb ports stopped working, i cant do anything with my imac besides turning it on or off, the keyboard and mouse arent doing anything so i have no clue what to do now if i cant use my keyboard or mouse. 😟

please help!

iMac with Retina 5K display, Windows 7

You should be able to

1. Use a Windows Safe Boot and rollback the removal, or install the USB3 host driver,

or,

1. Use the Windows Install USB and plug it. It has drivers which should allow your devices to work.

2. In OSX System Preferences -> Startup Disk, choose your Bootcamp (not the USB), click Restart.

3. It should boot from USB and allow you to repair the Bootcamp Drivers.

If Windows Safe boot is not working, then try the second set of steps...

1. Use the Windows Install USB and plug it. It has drivers which should allow your devices to work.

2. In OSX System Preferences -> Startup Disk, choose your Bootcamp (not the USB), click Restart.

3. It should boot from USB and allow you to repair the Bootcamp Drivers.

When you installed Windows on the 5K, you would have created a USB which had the BC drivers and Windows installation (The Windows installer could have come from the DVD directly or an ISO created from the DVD). Do you still have that USB Flash drive?

Can you post a screen shot of the USB folder structure from the Finder? It would look similar to the following.

The IntelxHCISetup directory has the necessary drivers when Windows is initially installed in the PE. If you boot from this USB, your Keyboard/Mouse should work. Notice the USB3Ver.dll file.

What happens if you boot from the USB using the Alt key while powering up the Mac?

Apple Tech Support wiped your iMac? 😮

This means you have to re-install everything from scratch.
