check the support matrix :

also worth check field notice :

Hi @TSR 

Below are the steps of 

Converting N9K from Cisco NX-OS to ACI Boot Mode, Using a USB drive.

Equipment Required:

1. Laptop with USB port access.
2. Pen drive (FAT-32)
3. Console Cable

Procedure:

1. Format a USB pen drive with FAT32 file system
2. Copy the ACI image in the USB pen drive.
3. Login to the switch and check the ACI image using below command

Switch# dir usb1:

(or dir usb2: depending on which USB slot you have plugged the drive into)

4. Copy the ACI image to the bootflash

Switch# copy usb1:<ACI-image-name> bootflash:

Note: In case of modular chassis e.g. N9508 etc.; If you have a dual-supervisor system, you have an additional step, which is to copy the ACI image to the standby supervisor module:

Switch(config)# copy bootflash:aci-image bootflast://sup-standby/

5. Upgrade the image using below steps:

•          Turn off NX-OS mode.
•          Make sure that the first change survives a reboot.

•          Boot the supervisor modules using the ACI image specified.

•          Perform a switch reload

Switch(config)# no boot nxos

Switch(config)# copy running-config startup-config 

Switch(config)# boot aci bootflash:aci-image-name

Switch(config)# reload

Once the switch is rebooted with the new image, you can log in.

I followed the same steps but no luck. Back in 2018 I did the same process it was working at that time but not now.

It should work. I upgraded less than a year back sans issue. Please recheck.

Did you format your pen drive using FAT32 file system?

I had this issue and had to load the ACI by breaking the startup and loading the ACI boot there.

dir usb1:
(locate ACI image and copy, if it states usb not found please use steps to format usb on the switch below)
conf t
no boot nxos
exit
copy usb1:/(ACI bin file) bootflash:
(wait for copy to finish)
copy run start
reload
(use control C to break the startup process once you see start up texts on the screen)
loader > boot bootflash:(ACI bin file)
(Should see a banner statement saying Converting switch from NXOS to ACI mode, reboot will take 15 minutes or so)
