Hi,

I installed Ubuntu 14.04 a few weeks ago and I was happy about it, but I need to sell this PC and I need to install Windows in it. The problem here is that I erased the recovery partition by accident and I can't install Windows with a CD because my computer doesn't have a disk case, the model of my PC is Lenovo Yoga 11s.

I tried to make a booteable Windows 7 USB with Unetbootin, but the BIOS doesn't let me boot from the USB slot. My BIOS configuration was in Legacy Support and my USB was the priority to boot. My USB was formatted in NTFS. When I open the boot menu it take me to the Grub of Ubuntu.

I don't know what else to do... I just need to install Windows, it doesn't matter if is 7 or 8.

I'd download the GPARTED .iso file [Google Search], created the disc using the burning program, booted to it and wiped the HDD then installed Windows. Since I couldn't boot to a Thumb/Flash drive I obtained an External USB Optical drive to do it. All the Netbooks I've worked with booted in such a manner, no other way to install the OS from CD or DVD.

The basic reason for wiping the HDD is that Linux [most versions] change the formatting of the HDD and Windows usually can't deal with it directly.

Windows will see and wipe Linux just fine, been using Linux since 2008 and Windows has never had a problem seeing ext2-4. It might just be a problem with Unetbootin, I would use the official Microsoft usb creator...

Microsoft Store

Another thing to check for is if you have "external drive [enabled]" in the bios. On my vaio I can set it to boot from usb but without setting "external drive [enabled]" it will not see any USB's.

Quote from this post: UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style). -> link

Normally, you should be able to delete all the partitions on the Where do you want to install Windows? screen.

Note: But if you cannot delete all the partitions on the Where do you want to install Windows? screen.

- Boot the computer using the Windows 7/8/10 installation media.
- On the first screen, press SHIFT+F10 to bring up the command prompt.
- Run the following commands at the command prompt.

diskpart
list disk (this will give you a listing of the disks on your system)
select disk # (select the disk you want to clean, for example select disk 0)
clean (running the clean command will delete all partitions on the disk)
exit

Even if you are going to use the GPT (GUID Partition Table), you do not need to run the convert gpt command, since you are not creating the partitions at a command prompt.

- Close the command prompt window and continue your Windows installation as usual.
