Are there any alternatives for OTLPENet.exe? I currently don’t have a blank CD on hand.

I think I might need a way to boot from USB. After I selected the ‘Repair your computer’ selection, it proceeded to 'Windows is loading files" and after the loading bar becomes full the screen turns black for a bit. This lasts for some time but eventually startup recovery loads, but what I only see is the blue background and cursor.

Would the RC being 32bit or 64bit have a large effect on the effectiveness of the boot from USB? I’m currently still seeing the Windows 7 blue background. Booting from USB only takes me to system recovery options, and after I select the keyboard input method it just stops at the blue background again. I’ve followed the guide as closely as I can and I’m not seeing the Win7 installation screen.

TwinHeadedEagle · 2015-07-27T05:20:20.000Z

Is your OS 32-bit or 64-bit?

system · 2015-07-27T09:40:39.000Z

I believe it’s 32-bit.

TwinHeadedEagle · 2015-07-27T10:33:19.000Z

Can you download RC 32-bit from this link?

Still experiencing the same problem. Instead of going to the Windows 7 install menu, it goes straight to System Recovery Options and requires the keyboard input method to be selected. After selecting it, no other pop-up turns up and it’s just the blue Win7 background.

TwinHeadedEagle · 2015-07-29T12:10:29.000Z

Did you try to wait a bit?

I just checked on my PC. When you select a keyboard, it has to search for Windows installation. Then you just press Next and you get to choose Command Prompt option.

system · 2015-07-30T08:14:03.000Z

I’ve tried waiting, but nothing much seems to happen.

TwinHeadedEagle · 2015-07-30T08:57:45.000Z

Did you try to plug USB into another port? USB 2.0 is more preferred. If you did everything good, then it has to work.

system · 2015-08-01T16:20:29.000Z

I used the USB ports located at the back of the CPU the past couple of attempts. I’m not sure why, it’s not quite working right.

TwinHeadedEagle · 2015-08-01T16:22:29.000Z

Are they blue (USB 3.0) or black (USB 2.0)?

system · 2015-08-05T05:06:07.000Z

I tried both, and both gave the same result.

TwinHeadedEagle · 2015-08-05T08:22:17.000Z

At this point I would suggest you to reinstall your Windows.
