1. You didn't specify the boot image in the configuration during the 1st time setup. 

You have to specify it as follow  

(config)# boot nxos bootflash:nxos-image-name
(config)# copy run start

After that, you won't going in 'bootloader mode' when reloading the device.

2. If you in the 'bootloader mode' use the following command to boot the image.

loader> boot bootflash:nxos-image-name

is this Lab or real environment :

1. Once you got nexus device # prompt, issue a dir bootflash:

  - it will show you the images in the flash as example below :

switch# dir bootflash:
       757307904    Feb 16 17:17:14 2017  nxos.7.0.3.I7.4.bin

switch# conf t
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# boot nxos bootflash:nxos.7.0.3.I7.4.bin
end
copy run start

is this virtual ? the VDC not going to work on virtual, so do not waste time, VDC works only Physical Devices.

You can find good information over Google and Youtube, since you learning, learn step by step can understand as expected.
